I bought a 2006 GMC Denali from this car agency. I drove it to Palm Springs. The next morning, the rear end of the car was 4 to 5 inches lower than the front end. The vehicle suspension system had collapsed. I had to spend $831.92 on the installation of a new air suspension compressor. When I first called the car agency to ask how to fix the problem they were cooperative. But when I called and told them the cost to fix the problem no one would even return my calls. I believe I should have been compensated for the cost of the compressor, since it went out the next day after the purchase.
