Diagnostic services service near Germantown, MD

I have taken several BMWs to Dan over the past 10 years. He is the most honest engineer you will ever find. His prices are reasonable and the quality of work is excellent. Don't bother going to the dealership unless you need a rental car and a cappuccino.

Wife and I have been customers for many years in one way or another and no complaints at all. Work performed over the years include oil changes, brake pads, brake shoes, rotors, ignition coil replacement, valve cover gasket replacement, radiator replacement, serpentine belt replacement...and no complaints! Not one single complaint! Rob and the mechanics at Airpark Certified Auto Service are top notch! They're reliable, they're honest, they're just a great group of people all around. It's comforting to know when the unexpected happens, like today, we have Rob and his crew to turn to for help. Support your local mom and pop businesses, especially when they're this great. There's no reason not to. I would refer anyone who is in need of repairs to contact Airpark Certified Auto Service and rest assured they are in great hands.

Had been going to this guy for 15 years. In April 2014 Took my car in, guy kept if first 2 weeks, didn't address the problem. Afterwards I had to return the vehicle 6 times and he still didn't repair the problem. Took the car to the dealer who found the problem and said GAC had installed a cheap aftermarket part (not OEM) that was incompatible with the vehicle that doesn't take aftermarket parts. This guy ripped me off and refuses to reimburse me. Also I asked from the beginning for the parts he replaced, he lied saying I never asked for the parts. He did the same thing to my daughter. I would never take my car back to this guy after the way he ripped me off.

We know your car inside and out!

Great shop with excellent service. I will definitely be bringing my car back next time it's in need of repairs. Can't recommend these guys enough!

I've been going to Marv & Mikes for over 20 years. I have never been disappointed. When I married, my husband was a "dealership " person. He finally became frustrated with prices and poor service. I'm glad to be back to using Marv & Mike. They never fail me.

“I was dissatisfied with the service provided as they failed to inform me about the need for a re-inspection. Upon returning, I was charged again for a new inspection because the initial one had expired. This caused inconvenience, as I couldn’t register my car at the MVA. Additionally, during the second inspection, they insisted on repairing a part of my vehicle that the dealer confirmed was not necessary. It seems they prioritize profit over genuine service, leaving me to cover costly repairs for something that isn’t even faulty.”and I have to bring my car i again to be re inspected so I hope this time pass and they don’t came out with something else !!
