As always the experience at Laura Buick GMC was excellent and we could not be happier with the vehicle we purchased. The entire team starting with our sales person went above and beyond to make sure we ended up with the vehicle we wanted at the best price possible. We have bought multiple vehicles from Laura Buick GMC and will continue to buy from them in the future.

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.
