My 2021 Mazda CX five never had problems until I took it to this shitty place as I was driving two days later my car started overheating. I had to take it with a tow truck to a real mechanic in Beloit the stupid people at Mark's auto shop they must be young kids smoking, dope or something. They put the stupid water pump belt on backwards that made my vehicle overheat!!! NEVER go there. Anyone they act all nice they're overpriced. Beware of that place.

They keep up with great communication while major work is being done. I had a timing chain replaced along with the water pump, spark plugs, and exhaust gaskets.

VinGogh truly saved the…read moreday and went the extra mile after a nearby "15 minute oil change" shop drained my CVT transmission fluid instead of engine oil. Very knowledgeable, nice, and easy to talk to staff that made a crummy situation way better. Great documentation with excellent communication and a very fast turnaround to top it off. they stayed late and had it all done very quickly for something so short notice. They even took a very noticeable collision dent out of my front bumper free of charge! I'm not saying expect free repairs, but they're great people who get the job done right. Couldn't be happier given the circumstances and I will definitely be taking my business here again.

Pricing is spot-on, you get exactly what you go for with no pressure to do anything extra. Shayne has replaced alternators, sway bar links, brakes, rotors, exhaust parts, etc on a few of my vehicles & I don't trust anyone else. Overall the best folks to bring your ride to.
