I am satisified with the services I got from here. My Audi A4s check engine light came on I didn't know what it could have been. I went to Firestone and they charged me $100 for a diagnostic they told me what was wrong but my warranty was over a few months ago so they told me an arm and a leg just to get my car repaired. I went home and searched for auto repair shop around McDonough and found D&D. I went there and I was given an estimate on my cars repair. Within minutes of having my car they hooked it up and found what made my check engine light come on. All it needed was a tuneup like oil change spark plugs changed and alignment. My cars did also tell me it needed that so I should have probly not waited because the results came back bad on that but they got it straight again! 373 mcdonough parkway mcdonough ga is where everyone should go!
