Ultimate Motorsports Shady Dealership Houston Texas

How do you express disappointment in a company that seems to have such great cars?  I purchased an Ebay car (2010 Volvo XC60) from Ultimate Motorsports on August 25; my sales rep was Kelli.  Initially, everything went well, she was helpful and responsive and she assured Michael and I that the car was in wonderful condition.  They shipped the car and when it arrived the problems began.  The body had damage that was photo-shopped out of the Ebay pictures.  We were shocked!  Pictures were taken immediately and sent to them.  It was so bad that we almost didnt' accept the shipment!  There were other problems too:  the motor mounts were cracked, the rear breaks were worn through the rotors, the service engine lights were on, the leather seats had huge knife cuts in them and the tires were bald.  I sent multiple emails and called them constantly to no avail, they sent me to the answering service every time and never returned phone calls or emails. After a couple of weeks of constant calling, they sent me $450 as compensation for the body damage which obviously didn't touch the cost of the work needed on the car.  They also made me sign an agreement not to put anything negative about them in writing anywhere. Now, 2+ months later I still haven't received my license plates!  I have emailed Kelli twice and of course, when I call, I get the answering service. How can such a shady company stay in business?  Buyer beware....I plan to call my finance company AND an attorney!
