We bought 'the most expensive used car on the lot'...

We bought 'the most expensive used car on the lot' and about 15 minutes after we drove off the lot to go home, we discovered the car was flawed. The passenger side climate control unit was inoperable. We contacted our salesman the morning of the next business day (bought it on a Saturday) and were told to bring the car in. They confirmed that the code showed the climate control system broke during the vehicle warranty (during the original owner's time owning it) and that the service manager would be in contact with us. We found out it will be approximately $3,000 to repair this issue. After numerous attempts to get to the service manager, to date, we still have not had a response. You would think spending just shy of $39,000 on a car from a reputable dealer would get you better service than this. Additionally, this is the 4th car we have bought from Len Stoler - NEVER AGAIN!!!
