College Park, MD
When I'm looking for a mechanic, I'm looking for guys who are knowledgeable, honest, and charge a fair price. These guys are exactly that.
I brought my 98 Honda Accord V6 in after it wouldn't start and these guys diagnosed the problem, were honest about all the repairs up front (i.e. what needs to be done and what doesn't need to be done), fixed the problem, and had me in and out within a day (at nearly $800 under what I would have paid at Pep Boys). Quick and painless - just how most things should be.
If you want to check out their competitors (as any smart consumer would), then you should. Just don't frown when you come back and see my car ahead of yours in line.
When you've found auto guys that treat you well (and as an extra perk are located a block from the College Park metro), you stick with them. I will - and you should too.
