OG Automotive (Shady Grove Service Center) in
Riderwood (MD)

Whatever you do, please do not take your car here for repairs. OG Automotive does not stand by its work and shamelessly forces its customers to bear the cost of its negligence. Please see below for incident details: On April 29, 2024, I took my car to OG Automotive in Derwood, MD, to have the turbocharger replaced. I supplied the part myself. On February 3, 2025, the check engine light came on, so I returned the car to OG Automotive. They diagnosed the issue as a faulty turbocharger. I purchased another turbocharger, and they installed it again. However, on March 13, 2025, the check engine light came on once more. I took the car back to OG Automotive, and once again, they diagnosed the turbocharger as defective. The owner offered a 50% discount on labor for the repair. At this point, I began to question the quality of their work— it’s unlikely that two turbochargers would fail in such a short time. I purchased another turbocharger and decided to take my car to Rockville Automotive for a second opinion. I explained the history of repairs done by OG Automotive. During their inspection, the mechanic discovered that two of the three bolts securing the turbocharger to the engine head were broken, and the third bolt was stripped. He advised that I return to OG Automotive, as the issue was due to poor workmanship on their part. I went back to OG Automotive and spoke with the owner, Oui. I informed him about the broken and stripped bolts, and he acknowledged that it was the result of negligence by one of their mechanics. I expressed my concern that I was never informed of this issue during the initial turbocharger replacement. He had no explanation. Subsequently, I took the car to a dealership, which provided an estimate of $4,000 to remove the damaged bolts and properly install a new turbocharger. I brought this estimate to OG Automotive and requested that they cover the cost, given the situation. The owner refused to take responsibility for the damage caused by his mechanic and denied my request. I ended up paying $4000 out of pocket to have the car fixed at the dealership.

OG Automotive is the place to go! I have been coming here since it was ran by the previous owner. And he definitely made the best decision to have these kind gents, Oui the owner and Bern & Risky open up their shop here. I have had ALL kinds of services done here. And let me tell you, they are honest! They will NOT try to be sneaky like many dealerships around here. They are upfront and if they don't recommend a service to be done they will let you know. Super easy to drop off, the customer service is just amazing. Its funny the other day when I was picking up my car, a customer was in front of me in disbelief of how honest and amazed he was with their work. Put a smile on my face because they are truly that great. For reference: 2013 Toyota Highlander

Amazing shop! Was from out-of-town and had issues on a Friday evening - looked up nearby auto shops, walked in to OG right before closing, and they made sure to get to it the next day (so I didn't have to extend my trip). Honest & transparent pricing and really really nice staff. Thank you very much!

It’s one of not many places in the area that service Maryland State Inspection on Saturday. Better call before bringing the car tho. The place is packed! Love the guys there!

So happy that this shop was recommended to me. I do most small work myself, and am skeptical of having someone else work on my vehicles. I was pleased to find that the technicians at OG Auto share a passion for vehicles like I do! You won’t find this at most shops nowadays. The staff heard me out and shared concern over all of the issues- and potential issues I was having. Right away I could tell they were very experienced in their work, and fair with their prices! As long as I live around the area, this will be my go to shop. 10/10 recommend!

This shop worked hard and was very professional repairing my Hyundai SUV! The owner also was very thorough and eager to help me figure out an issue I was having. This is one of the few repair places I recommend!

Great service, the owner is very friendly and is very knowledgeable. Have brought vehicles to this shop several times and have also had friends and family members come in for service. Everyone has had a great experience and have been happy with the work being done. Never over charged for unnecessary repairs. Thank you for the work you guys do !

Oui is an awesome mechanic. He is the only person I trust with my Porsche 928. It’s not an easy car to work with. He replaced my transmission, rebuilt my torque tube with super bearings, rebuilt my steering rack, rebuilt all the fuel injectors and vacuum hoses, fuel lines and power steering lines. The car drives like magic now and puts a smile on my face every time I drive it. When I came to pick up the car - he had done many minor things that he didn’t really charge for. He had sand blasted all my intake lines and gotten them shiny, he has cleaned a lot of the engines area and painted some of the engine parts that had faded like the cross bar. I now bring all my cars here. Reasonable and hard working people. I would recommend them 100%

Oui and technician crews did an excellent job! It was worth every penny to drove 1 hour from VA. Over 25 years of his experience would make you happy 👍.

customer service is the greatest I ever experienced. They were so nice and easy from the guy at the front desk to the technician they were very thorough and helped me work through the issues that came up and got me squared away in an efficient quick manner

Courteous, quick and professional. They installed side steps for my suv in under 2hours at a very reasonable price.

Oui the owner and Bern the service advisor here at OG Automotive are some of the most helpful, kind, efficient and honest mechanics I have ever come across in my 20+ years of car ownership. I implicitly trust them with all of my vehicles along with my family and friend's cars. I can't recommend them enough, I have no need to take my vehicles anywhere else and you'll be extremely happy with the results! Thanks again for everything!

When Bill McCurry closed up shop shortly before Christmas 2023 I had no idea where to go to have my car serviced. After a couple false starts I said “Why not!” and went to OG Automotive after a really bad diagnosis on my 2007 Lexus IS. 250. Bern and The Magician (The lovely owner) not only knew a fix for what could have been a very expensive repair, but were positive about the life of the car going forward as well. In addition both men are highly knowledgeable and very kind. I’m glad I went back.

I've been a customer of the new owner - Oui - for many years. He is one of the most competent and honest people I've ever dealt with. He is also kind of shy :-). So, in tandem with Bern, the service manager, who is also very competent, but also a great communicator, everything works perfectly. With Oui I've never had to worry about my cars.

A rare find! Bern & We run this new shop, used to be Bill's. The new shop is terrific with reasonable prices, fast service and fun conversation! I'm returning. Give them a try!

Bill McCurry is the most knowledgeable, honest an capable mechanics I've werner known!!!. We've been going to him for more than 20 years

My daughter's car has been repaired 3 times for left front wheel brake and road noise problems without success. Bill repaired it and it runs like new. He will get all of my business from now on.

As far as I'm concerned this automobile repair shop is one of the best in the area. His prices are very reasonable. In addition he is Honest, and gets the work done in a reasonable time. I was referred by a friend and I'm so glad I took my car to McCurry's

Great experience using Bill McCurry's shop while we lived in MD! He was always super professional and things never seemed to get backed up or delayed. His recommendations were always top quality, even if it wasn't lowest price around. Never had an issue trusting this shop with our vehicles.

I cannot say enough about Bill McCurry's Service Center. If you want someone that you can absolutely trust with your car there is none better! As honest as they come!

Bill is great, we have been taking both our cars to them since we moved to the area. A 2006 Toyota Prius, and a 2014 Honda CRV. Always responsive, and honest. Plus quick walk to metro to get to work downtown. Highly recommend.

I have had nothing but great experiences with McCurry's. Bill is honest, knowledgeable, and they do great work. The shop is conveniently located a short walk from Shady Grove metro to boot. Everyone that I've recommended McCurry's to has had equally positive experiences. Hands down the best garage I've ever taken my car to.

All in all this was an easy, reasonably fast experience and not too expensive. I had to get my vehicle inspected, having come from out of state. The service was friendly and I left without feeling I'd been pressed toward more expensive work. My car passed inspection just fine and I'll be bringing my other car in for the same job next week.

I must say that I was disappoint in my service. I went for an Maryland State Inspection and was giving a list of thing to fix. The list was reasonable. Got it fix and came back and the shop broke the battery case and failed me for the broke battery case. but kicker was a now disclosed charge for a re-inspection fee, in addition to lost the original inspection paper showing the things that need to be fix. I relinquished minds my copy a curtisy so they can have something to go by and never got it back. The re-inspection fee is a sort of a conflict of interest for an inspector to charge. BUYER BEWARE, there may be a sliding scale charge that may apply to your service, which lead you be charged more that the quoted price.

I have visited Bill to have 1 of my newer cars inspected, his pricing for MD state inspection is pretty fair compared to others in the area. Since the car was relatively new, it did not had any issues and passed with flying colors. During my conversation with him during my initial visit, I found him to be a genuine person and some one who would not take undue advantage or misguide you in any wrong way. So I decided to inspect my other older car (from 90's). As I have heard lot of horror stories about it, i knew that he might find something and was ready to get it repaired. My car had some body damage and the other shop in the area told me that I need to fix the body before it will pass the inspection (which I didn't feel was true and would have costed me almost 500$). The car passed with no mechanical issues. I think he's a honest person and I will definitely go to him for any other issues on my car. I highly recommend his shop to anyone.

ok, right up front: i am not a car person. i have all the recommended maintenance done on my car, but i certainly don't know how to take it apart all across the driveway myself. time and again, i've had the experience at a repair shop where they can apparently tell right off that i'm not an expert, and i end up feeling run around in circles, unsure of what NEEDS to be done vs. what's optional, and simply overcharged for whatever i do end up getting done. this is why i have been taking my car only to Bill for the past 4+ years. he will give you a call once they have looked at the car, and explain what's wrong and why it needs to be done, and give you an estimate before they do the work. his explanations are clear and reasonable, and i always end up understanding what's being done with my car rather than blindsided by a bunch of suspiciously overly technical jargon. the good ol' boys that i work with (car guys to a one) that have seen my invoices from McCurry's are impressed with the labor rates, and tell me that it's a very fair deal for Montgomery County. as an added bonus, service is quick, and without any of the "well, i'll see if i can work you into the schedule in a couple days" rigamarole. with only rare exceptions, if i drop off the car the night before, i'll get a phone call with the estimate by lunchtime the next day, and the car will be done by 5pm the same day.

Been twice to McCurry's Shady Grove Service Center . Pretty impressed by the service they offer. Excellent professional service and very friendly people. I would certainly recommend. (also noted they offer an honest maryland state inspection at a lower rate than nearby by shops)
