They did the repairs.

Entrusted this shop w/ work on a recently purchased Jeep. Work was completed in good time and done extremely well. Will absolutely use again. Good to find a trustworthy shop that does good work. Dan K. St. Louis, MO

Mark and his entire staff are great people to deal with. They are friendly, honest and knowledgable. The pricing is fair, the service is top notch. You need to take your vehicle here for all your repair and maintenance needs. I use their new Ellisville location. My brother and his entire family take their vehicles to the Fenton location. We love them for their friendly, honest dealings, fair pricing and great work.

Remembering back to the day Don opened. It is because of his great service that he has allowed his business to grow and become a pillar of the community. It is truly hard to find service shops like his that care about their work and stand by it without overcharging and finding things that don't really need "a fixin". I highly recommend Giannini's Auto Service for all your auto repairs and needs. Jim Privitor Kirkwood, MO

I took my car here and the guys were able to tell me very quickly what was wrong after I had taken it to 3 other shops who could not figure the problem out.

These guys rock! Took the time to explain my front end repair. Even took me to the vehicle to show me. I trust them completely. It feels good that I can take my vehicle to a place that's not out to take me.

Amazing customer service! I was given a breakdown of services I would need ..they even offered discounts. They were really honest and answered all of my questions. Also given their opinion on which services I should prioritize since I wasn't able to pay for all of the services that day. 100000% would recommend to everyone. Especially if you're a woman because I didn't get the vibe that they were trying to take advantage of my lack of knowledge. Leanna B. Saint Louis, MO

Best place to bring your car, I have a $90,000 BMW and trust these guy 100%. I walk in I get treated with respect, everything is very well explained and they are very cautious with my car....love this place!! They have one of the best welder s I have seen...flawless welds!!

Horrible service did terrible welds used a smaller pipe than the original to connect two pipes that don't even fit. don't take your car here waste of time. Blamed engine mounts when they had been replaced and are within spec. When the entire job in the first place was bad. Refused to fix it and kicked me off the property. You can see in the photos the welds had holes in it to begin with. Absolutely unbelievable
