Emissions testing service near Hamilton, OH

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.

Honest Mechanics I thought I needed new brakes, after an inspection just needed a flush and a adjustment.

EXCELLENT SERVICE I was having issues with a previous mechanic due to constant rescheduling . I have always dreaded going to a mechanic due to various shops taking advantage a a woman who doesn't know much about cars . I then stumbled across wrench and decided to give it a try . Ray showed up and he explained my car issues in detail . He was sincere and extremely knowledgeable. He was able to figure out my issue and fix my car in the same day . I also learned new things during my interaction with him . I will continue to use wrench in the future and recommend wrench to my peers . THANK YOU !! Keeshia L

High quality auto repair in Cincinnati OH

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.

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!
