Mufflers repair service near Wilmington, OH

There needs to be a whole lot more stars to properly rate this automotive repair shop. I'm thinking about 20 might do it. Thanks to Ben and his entire staff for EXTRAORDINARY service! Dr. Kathy P.

I brought my high mileage Mercedes here after it decided to not want to start. What is great about C's Autohaus is what they didn't do; they didn't try to take advantage of me because I'm a Mercedes owner, which up until now, I thought was some kind of code for moron to repair shops. I'm used to taking my car in to a shop and having them try to sell me thousands of dollars worth of useless repairs with highly inflated part costs. C's Autohaus was able to diagnose that it was just the starter motor, and replaced it at a responable price. They were also able to find and fix an oil leak the same day at, again, a reasonable price, and they fixed some minor performance issues while they were in there gratis. After those repairs my fuel economy went from about 10 l/100km to around 7 l/100km (smaller number is better). The shop itself is pretty cool too. They have a lot of old VWs from the 60s and 70s on their lot which I'm guessing are project cars.

The staff and service was outstanding.

Took my SUV in for service to check a sputtering transmission. I was told I needed to repair a vacuum leak and battery which cost $800. Less than three weeks later the transmission went completely out and they charge me another $140 to tell me the transmission went completely out. The original missed diagnosis cost me $800 plus a towing fee and then they had enough nerve to charge me another $140 to tell me that the transmission was bad. When it was obviously bad three weeks prior and they just wanted to suck $800 out of me for other services. Unethical. Stay away.

I can't say enough about the professional service every time I bring in one of my Mercedes. For both old & newer cars, diagnosing the problems, finding the parts and fixing everything to perfection, with personal attention, is a perfect combination. Ricky & his team run a great organization and I recommend them to everyone!

I’m a new foreign car owner and I take my car here . If you guys want things fixed correctly and done correctly GO HERE !!!!! Thank you guys so much foreign exchange !!!

It is a shame to say things about a person or place you know nothing of or nothing about because you did,t go by the warranty or didn't give him a call. first of all Allan has built engines over 40 years and i have never known he to be dishonest nor not willing to make things right if something was wrong.people like Kevin combs from Texas never sent warranty papers back nor told Allan what the problem was just asked for money for repair with out estimate i know cause i was there when Kevin called him. I bought the 496 stroked anyway and I'm very happy. the way i see it is Allan is honest and fair. when something goes wrong it is always the builder not the person that waits 2 to 4 yrs later to complain after he messes something up i got 1 yr warranty ,warranty papers that tells you what you have to do just follow the directions that you did NOT read then you would not have these problems.by the way Allan builds over 100 engines a year every one knows he backs up his work so please before you tare some one down know who he is remember he builds engines you don't that's why you bought engine from him .by the way Allan does not work on cars as work advisor says he just build engines /get the facts right

All Speed Innovations aka Sigma Six Engineering is ran by a wanna be engineer named Pat Smith. Pat uses customer cars as his personal cars while in for service. They charged me for a alignment and the alignment wasn't done. They also took it to a alignment shop without my permission. When they installed plastic TGV deletes they connected a ground wire to them. Pat couldn't figure out how to connect his laptop to my car and disable the TGVs, I did this myself after reading how to do it on the Internet. They also built a cage for a customer and ruined the customers car. Everyone should stay away from this shop or anything related to what Pat Smith does.
