Genesis of St. Charles review
Working with Milan Venezia at Genesis of Saint Charles was honestly one of the easiest car-buying experiences I’ve ever had. He made the whole process smooth and stress-free. It went so well that when my fiancé said she was thinking about getting a new car less than a week after I purchased mine I didn’t think twice—I called Milan right away. From start to finish, he was super helpful, honest, and even funny at times, which made the experience that much better. Even the finance guy was cool and easy to work with. And I thought it was pretty cool that a concierge walked me through all the car’s features before I pulled off the lot—great touch. If you’re looking for a dealership that’s honest, has great service, and a clean, welcoming vibe, definitely check out Genesis of Saint Charles and ask for Milan Venezia. You won’t regret it.

Sapaugh GM Country review
I felt they were honest 1st of all. Can't say that about very many dealerships. They gave the best trade-in value on my 2015 Tahoe (by far). I searched Missouri and Illinois for about 8 weeks and Sapaugh was the best experience Hands-Down. My ONLY fault with my whole experience was getting my paper work finished. It was a cash deal with a trade-in. NO financing needed. But it was a holiday weekend (01/02/2026) only one guy doing the paperwork processing instead of two. NOT a giant deal.

Autos of Chicago review
I highly recommend Autos of Chicago for anyone looking to buy a used car. The team was professional, friendly, and very easy to work with. They offered a good selection of quality vehicles at fair prices. Everything was handled quickly and transparently, from test driving to final paperwork. It was a stress-free experience, and I’m extremely satisfied with my purchase.
2021 GMC Terrain review
READ PLEASE I love my Terrain. DO NOT get the 1.5 L. My engine has barely made it over 100,000 I have had $6k of repairs in less than a year. Things keep going wrong now. I had NO issues before. Catalytic converter went out 75-85k miles. My turbo was just replaced. Just beware of this type of engine… every mechanic that worked on it shared this is not uncommon for this type. I would definitely get another terrain but not the 1.5!

Jim Trenary Chevrolet Buick GMC review
The quality of service, and such helpful customer service, was exceptional. I would recommend this dealership to everyone. They also helped several months ago when I needed to replace my tires. They helped me get a quality set of tires at a very affordable price.

Clement Ford review
My fiancé bought a new Ford from Jim Fox, and we had nothing but a fantastic experience with him. Give him a raise!
2021 GMC Terrain review
Bought it used. The shifter on the dash takes getting used to. But after a month I no longer grab for the shifter arm. Have been happy with comfort. Driving. Gas mileage. Would recommend it.
