If you want to purchase a verified Carfax vehicle, go to Post Auto Sales. Greg takes away the stigma of a used car sales. As a Veteran, Greg clearly brings to Post integrity, ethics and morals that is never experienced at auto dealerships. No pressure to upgrade, clear and honest answers and very friendly and personable. My experience purchasing my Ford Escape was absolutely WONDERFUL. Greg does everything he can to take care of his customers. Thank you for an honest, ethical and great experience. Most of all my heartfelt gratitude for your service to our country.

Amber Campbell

A great experience with Greg and we will definitely look again for future vehicles.

Jeff Smith

Greg is a very honest auto salesman. Stands behind what he sells. I WILL be back again one day for another vehicle. Thank You Post Auto!

I recently purchased my very first vehicle from Greg at Post Auto Sales. Going into the process, I had some anxiety and concerns buying a used car. My knowledge of cars is very limited, so I felt I would be at the mercy of whatever dealer I was working with. Thankfully, I found a very trustworthy one. After almost a month of research, I found the car I wanted, an Orange Pontiac Vibe. At no point did Greg try to up-sell me or push a different vehicle, though he was very friendly and helpful and I believe he would have thoroughly walked through every car on the lot with me had I asked. Less than a week after purchasing the vehicle, I noticed new noises coming from the exhaust area. When I mentioned the noise to Greg, he encouraged me he would do the right thing and take care of it, and that all it would cost is my time stopping by again. While it ended up just being a lose screw on the heat shield above the muffler, he had made his offer before knowing whether it would be a simple fix or not. Overall, my experience with Post Auto Sales was extremely positive and I highly recommend them!

My fiance and I contacted Post Auto looking for a vehicle. We are just starting out and this would be the first car we would purchase. We both have Zero credit. During the whole approval process he was kind and professional; even though ours might not have led to a sale because of our credit. We are still going through the process of approval but even if we are not approved I would highly recommend this small dealership.

I just purchased a Ford Escape from Post Auto Sales. Greg was super nice and down to earth. He was honest about what he is as a business and will share with you all he knows about the vehicle and more. I highly recommend him as he is a veteran and donates generously! He prices things comfortably and the warranty included is great!

Jessica Frye

Greg was very honest about everything and he wasn’t pushy. He offered to let us put the car up on his lift to get a better view of the underside. He provided us the carfax and answered everything about the vehicles history. He gives a 90 day warranty on all vehicles and his price was the best price we found in comparable vehicles.

Nick Jakubowski

This dealer made me feel more confident in purchasing a vehicle then I have ever felt buying a car anywhere else. Definitely stands by his word when he says he is NOT an ""as is"" dealership. I am very happy with my purchase!

Tera Armstrong Smith

We bought a car for my daughter Let’s just say the owner greg went out of his way for me!! Nice guy...very honest. Would go back.

Dawn Cronin

Greg is very honest, has integrity, and will do the right thing to make the customer happy. Purchased a 2012 Kia Optima on Saturday, 7/20 that had a little glitch and he had it fixed and ready to deliver on Monday. I have bought a lot of used cars and never had the pleasure to deal with a more upstanding person. If you are looking for a good used car, drive to Deerfield to Post Auto Sales.

Anna Stuiber

Greg is very honest and helpful. He offers a 3 month warranty on every sale. Upfront and fair pricing.

Jace Smith

Greg was amazing, no pressure sales and quality vehicles at an affordable price would buy again from him in a minute.

Karla Richter

I just purchased a Land Rover from Greg. He was honest and worked with me to get this car. I picked it up today and love it. I have already recommended two of my friends to go check this awesome place. Thank you so much Greg.

Heather Hoemke

Great place. Very nice, took time to go over the car with my son even took us to his lift look under the car. Would highly recommend!

Heide Keith

Post Auto Sales will be my first stop next time I need a vehicle. I purchased a Jeep from Greg last month and came away feeling I made the right choice in vehicle and dealership. Greg shared all he knew about the vehicle without the car sales hype. I quickly got the sense he wants to build a business with repeat customers. It's because of how he conducts his auto business, that I will return. And I will encourage my friends to visit his website.
