I would highly recommend John Lipe and Robert Booth. Fair pricing, friendly people and great service.
One of the best looking suv's on the road. Highly
Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

absolute best car buying experience i have ever had.
absolute best car buying experience i have ever had. No pressure tactics, no games, and Eric Finion was the absolute best salesperson. Helped me get the car i wanted at the price i could afford. really can't say enough good things about this dealership.
Grea4 mileage and comfort
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.

We bought a used Hyundai couple of weeks ago.
We bought a used Hyundai couple of weeks ago. I think we got a good deal. The dealership was a good experience, specially compared to the other places we had been to. The sales person Christian Gonzales was extremely friendly, helpful and cooperative. His manager Renato Garcia was also a nice person to work with.
Try this SUV before you buy another!
Frank Kent in COrsicana, TX gave me a great deal on my trade-in and on my new Terrain! I was intending to by a VW Taos that morning but when I saw the Terrain AT4 and drove it a little, GAME OVER ! I came home in the stylish and comfortable AT4.

On April 30th, I brought my 2018 Chevy Equinox to
On April 30th, I brought my 2018 Chevy Equinox to Advantage Chevrolet of Bolingbrook for routine maintenance and an oil change tire rotation. Their team of mechanics, Dylan specifically, and your service consultants Jimmy, Ray Jr. and Renee are truly exceptional, and I am immensely impressed by the level of professionalism and expertise I have experienced at your dealership throughout the years. Maintaining three Chevy vehicles can be quite a task, but the team at Advantage Chevrolet of Bolingbrook has consistently gone above and beyond to ensure that all of my cars are in top-notch condition. It's evident that they take pride in their work and are committed to delivering the best service possible. Their dedication to excellence has not gone unnoticed, and it has undoubtedly contributed to my continued trust in Advantage Chevrolet of Bolingbrook. I have peace of mind knowing that my vehicles are in the hands of experts who genuinely care about their customers. I?ve said it before and I?ll say it again, they?ve got a customer forever! Once again, I'd like to thank them for their exceptional service and for the peace of mind they provide as a trusted service provider. I look forward to continuing our partnership in the future. Jim McIlvain Downers Grove, IL.

Main Street best used car dealership in Valparaiso
Amazing people, Main Street Motors is the hands down best used dealership I have ever purchased from. My car has 50,000 miles and they had brand new tires and brakes put on the vehicle with a fresh oil change. Can't say enough about the people here.
There are 20 matching cars close to your year range.
