We went there on a Saturday morning and were approached by Andrew. We talked about what we were looking for and he got a vehicle for us to test drive. We weren't fans of the first one. We told Andrew what we did and didn't like. He brought out another vehicle to test. We loved it! When we got back, we started the process of buying it. That process always takes longer than we like, but we don't have to do it very often! We did everything that Andrew needed and then we had to wait for the finance guy. We were paying cash and were not purchasing an extended warranty that day. That didn't matter - we still had to wait and go through the process. Grant was the finance guy. He did go through everything quickly after we told him where stood on the warranty issue. He was pleasant and very efficient. I love my new vehicle! Andrew called four days later to see if everything was okay and to see if I had any questions. I highly recommend this dealership and Andrew and Grant!

Due to recommendation, I had the car towed to Mastertech Auto in Ellisville, MO. I was told they were honest and had a lot of integrity. Well, that was absolutely the truth!! I really could not believe the service that I received from this place. I dealt with Rick and he couldn't have been more honest and realistic about what was wrong with my car. Further, he didn't keep me waiting. His assessment was quick, he called me when he said he would and he followed up with me in the exact timeframe he committed to. Breaking down and being stranded is no fun, but Mastertech and Rick definitely made this experience a heck of a lot better. I hope you guys see this....Thank you for your help!!!
