I ask why and the lady says we didnt even charge you the full price for the extra time it took to get the rusty bolt off. Anyways I paid and drove off. car still seemed loud i look under the car and the exhaust pipe is dangling from near the rear muffler. I look under the hood and my exhaust manifold heat shield is also missing. This guy couldnt bother to tell me the exhaust pipe also needed a weld. It gets even better the work he did didnt even last a month. Car now sounds worse then when I gave it to him except now hes broken my manifold bolts, destroyed my heat shield and charged me $800 for the work. Dont be fooled by him calling you multiple times to tell you what hes doing...hes actually just making sure he informs you he will be charging extra. If you want a mechanic who will just do the bare minimum work on your car that it needs this guy can do it and will be ok to use your parts. If you want a mechanic who will look your car over as a courtesy and let you know what else is an obvious problem and build a long term relationship with you then this is NOT the place you are looking for. Hes also very expensive for what he does. There are other options in Dover

And to add insult to injury doing so about 10 minutes after most shops closed up for the day. **ENTER INTO THE PICTURE: John and Master Automotive Diagnostics** After giving John a run down of my problem over the phone, he was able to quickly troubleshoot the problem to include identify the root cause (a bad tensioner), call several stores to confirm availability of parts and provided SUPERIOR & QUALITY service. Not only was the service quick (considering working away from the comforts of a garage) but it was thorough, cost efficient, affordable and above all else, his customer service and communication skills were unparalleled. He was able to ease ALL worries, fears, and concerns within 10 mins of talking with him. He reassured me that I'd be home with my family within no time and that was warmly felt and received. I hope to never break down on the road again but he is HIGHLY RECOMMENDED and the FIRST call to make for anyone needing car repairs or is stranded on the road.

From the minute I walked in, I could see this was a serious shop! They put all my info in their system and the computer will automatically send me a text when it's time for service and it calbrates it's notifications when it understands it's waiting too long or not long enough It learns to adjust. Work I needed was carefully explained especially when there is a cheaper route that they didn't recommend, and I was explained why the more expensive route was best and offered ways to complete the work over time, at my own pace if I didn't want to spend that much at once. I don't know much about rotors and even after just 1 visit, I had no doubt that what he was recommending was for value over cost and without hesitation, I went with their recommendations. That is what Ilike best! service is fast, and they are all super friendly and courteous and the prices are correct.

They are very versatile. The estimate was very fair and they stuck to it. Great Serviceread more

The repair was done by brushing paint over the site and applying a substance of some type at cost of $1600 - entirely out of pocket.

Took my car here for a check engine light after pep boys told me a solenoid needed to be replaced and they couldnt do it. The owner Chris re-diagnosed the the problem and agreed a solenoid needed to be replaced. He charged me almost $800 dollars and when I picked the car up the check engine light was still on and I now had a completely flat tire. Chris tried to tell me the tire was probably already leaking before I dropped it off despite me having driven hundreds of miles with no issues over the last several weeks. We then discovered there was a nail now in the tire that one of his employees had driven over in their parking lot. They patched the tire and told me they would fix the problem. Chris calls me 2 days later saying now he thinks its just the wiring but it will cost another $600 dollars to fix. He stated its not his fault he didnt fix the problem correctly the first time since "I told him to fix the solenoid" even though he called me and said he diagnosed that as the problem as well. He finally fixed a wiring issue after a week of working on the car and charged an additional $600 because he could figure out the problem the first time. The professional thing to do would have been to correctly diagnose and fix the problem the first time like a competent mechanic instead of becoming defensive and blaming the customer and the charging them twice for your own incompetence. If I could give 0 stars I would TLDR: I asked this guy to fix a check engine light. He couldnt figure out the problem, blamed me, popped one of my tires and charged me twice. I will never go back. Please do not waste your money here.
