Disappointing experience purchasing a $150K vehicle! So many reasons for a subpar experience: 1. Everything was handled at the Chevrolet showroom when I was there to purchase a top of the line Cadill So many reasons for a subpar experience: 1. Everything was handled at the Chevrolet showroom when I was there to purchase a top of the line Cadillac. 2. I was discouraged from inspecting the vehicle prior to signing the sales contract. When I finally inspected the vehicle, I discovered the rear bumper was not fitted properly despite the sales person telling me that the vehicle inspection team knows what they are doing. The TPMS is malfunctioning as a result of the dealer incorrectly installing the sensor at the time they replaced the factory wheels with the 24in wheels the vehicle was optioned with. 3. Sales person lacked product knowledge - he did not know whether the vehicle was equipped with a spare tire or had run-flat tires. He was also unaware of the headphones that were included with the entertainment package the vehicle was equipped with. More

Greg and Mario were instrumental in making sure I got into the right vehicle. While, it was a stressful process because I did not want to get rid of my Silverado, and had a tight budget given I just boug into the right vehicle. While, it was a stressful process because I did not want to get rid of my Silverado, and had a tight budget given I just bought a house, they made sure they were doing what they could to find something that fit my needs. Ultimately, I ended up in a 2025 Chevy Colorado that fits in my garage which was utmost importance. I was sad to see my Silverado go, but life has a funny way of changing and the team at Mark Chris made sure to take care of me. More
