Diagnostic services service near Aberdeen, MD

Call ahead if you can. Shamrock has worked on 3 different vehicles for me. most recently repalced wheel bearings on my explorer. rapid service, reasonable price, actually was about $75.00 LESS than i was quoted and expected. the difference in the handling of my vehicle was amazing and noticed within seconds of pulling. the owner (?) is knowledgable and willing to explain what is going on with your vehicle. He has my business and I'd suggest him to anyone I know

very helpful and accommodating

Very Disappointed. I had Higher Expectations. I used to work here, so I had very high expectations when I referred a friend here. A freind of mine had a 2002 Mercedes CLK with an intermittent ground on the lighting circuit, but I did not have the time to troubleshoot it in his timeframe, so I recommended All Phase. I had great confidence in them to perform such a basic diag, finding an intermittent ground. Terri told him the diag would be $175, which was fine, and that they'd need it for a day or so. No problem. The next day my friend told me that when he picked up the car, Terri told him that it needed a rear body control module for $1300, and if THAT did not fix it, they'd be happy to replace the front control module as well, for another $1400. I used to work with Jerry, Dale and Terri, so when I refer someone, I don't expect to be made to look like an ass. They basically charged my friend $175 to tell him they had no idea what was wrong with his car, but they were more than willing to spend his money guessing what the problem was. Jerry, Dale, Terri. I want to thank you for making me look like a fool, and possibly a crook as well. That's pretty shitty especially when I thought we were friends, but I guess there's a sucker born every minute, right?

I've been going to Haris for years. The guys there are all very professional and courteous. I recently have some problems with my transmission and they were able to save my transmission by changing a couple of solenoids. Other shops would have tried to sell me a complete transmission for thousands of dollars. I was back in my car the same day and it only cost me a little over $400. I highly recommend this place. Manny and Guys are awesome.

Service was prompt and great price. What I appreciated most was that they did not try to upsell me on extra unnecessary parts. I had been going to Jiffy Lube which is similar price but they ALWAYS get you before you leave saying your brakes need changing when they are fine or last time they tried to get me for $250 saying I need a new cabin filter which is crap?! R&M is a small shop, but they get what you need done and honest about it.
