Customer service is great before you buy, afterwar...

Customer service is great before you buy, afterward not so much. My wife tried to buy a used truck, drove it off the lot, and for the next two months they cannot find a lender so they try to get us to sign a different contract with higher interest.
The second time we signed a different contract with $40 increase in monthly payment, we were told this is the final approval, the woman bringing out papers for us to sign was extremely condescending when I asked for confirmation that this contract was indeed, final. She said very rudely "I told you four times this is the contract", but since being two-faced is how dealerships do business, I let it pass. A couple weeks later we got called in for the same thing. Lender doesn't approve (even though we were told the contract we signed two weeks before was final), the new contract is a much higher interest rate. We ended up returning the vehicle. The advisor who cheerfully assisted us when we initially walked into the lot (Duy Tuy was his name if i remember correctly) gave us the cold shoulder and hid in his office the whole time we were there. Also he refused to pick up the phone when we called. Avoid this guy like the plague.
Do yourself a favor and find a different dealership to buy your car from, avoid the headache and lack of professionalism. It also doesn't help that there's a wild herd of salesmen always congregating around the front door, staring at you when you pull up, that should be enough reason to turn around and leave.
