I am so grateful to have found Schomp!
I am so grateful to have found Schomp! My car was totaled recently and, being a young woman who knows nothing about cars, I was BEYOND overwhelmed at the idea of buying another. I visited a few other dealerships, but I didn't like how "cornered" the sales teams made me feel. Schomp is SO different. I had the pleasure of working with Jacob at Schomp Honda in Highlands Ranch, and he was incredibly patient and kind while assisting me through the entire process, which meant SO MUCH considering how overwhelmed I was. I never once felt like he was trying to pressure me toward any particular vehicle or that I was being swindled to pay more, because that's not how Schomp works. It was clear to me that Jacob (as well as the rest of the team) wanted me to feel comfortable in a car I really liked, and he literally went out of his way to help me find it. Thank you so much, Jacob! Shout-out to Hayes, David Cole, and James as well. The people here are genuine, honest, and trustworthy which were major factors for me in letting them help me find my new car. This place greatly exceeded my expectations. The vibes are immaculate. Love you guys.

Was a bit put off by the fact that there’s one number for all Carmax is and. It’s hard to tell which location you’re talking to and if you’re talking to a person at that actual location. I understand they’re trying to consolidate things and make it easier, but I want to be able to reach someone, boots on the ground, at the location instead of talking to The call center. That said it seems even when talking to two different dealerships somehow the system sort out the messages but again it’s confusing. Overall, they were fast and friendly, we haven’t done a transaction yet but one thing that was surprising is the offer they gave me 10 days ago has now gone up by $1500. Much better experience than I had braced myself for frankly. So far the two cars that I was hoping to purchase turn out to be duds as they had some excessive wear and tear in spite of low mileage and otherwise good conditions. Maybe less discriminating on their inventory than the other dealers?

Great experience, would recommend
Great experience at CarMax Wichita! We worked with Sales Consultant Vernon Nelson and he was kind and helpful throughout the entire process. We felt zero pressure from him, which was a stark contrast to another dealership we were working with who pressured us hard and had an attitude when we didn't buy on the spot. Vernon just wanted us to have the best car for us, regardless of whether or not that was from CarMax. They offered us a fair price on both the trade-in and the vehicle purchase itself as well, so no we'd have no hesitations recommending them to others.
best in class
My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

Everything was negotiated by phone and email.
Everything was negotiated by phone and email. I was done and not expecting to buy because the cost was slightly more than I was willing to spend. The dealership is approximately 170 miles away. Finally, and after I had given up, David Messanio made an offer I was willing to accept but he wanted me to make the purchase within 2 days. I agreed to drive to physically look and if satisfied, purchase the truck. Once at Vacaville GMC, I was warmly greeted and treated friendly yet professionally by the entire staff there. The purchase went off without a hitch. I would recommend Vacaville GMC and the team there to anyone.
This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

Great team
Due to the current truck shortages dealers have been adding $5-15,000 over MSRP but you guys stood by your MSRP price. They also met me in NY at airport with my truck to save 5 hours off of my return drive. Couldn’t have asked for a more simple process and great team to work with. Thank you for all the help.

Van Horn is a Wow!
I dealt with Van Horn on an SUV for about a week. The vibe was so good that I ended up driving 900 miles on a Tuesday to make a purchase with them. I buy a lot of vehicles and I have never seen people stand behind their vehicles with such customer care and loyalty. They will earn your businesses.Very, very impressed and happy with their first class service and amazing warranty. I highly recommend Van Horn Chevrolet and their sales team.
