Texas Direct Auto  - fraud and scam

My husband and I flew from Alabama to Texas to pick up a car purchased online from Texas Auto Direct. When we got to the dealership they informed us that they had lost the key to the BMW Z 4 we purchased. Then they offered to purchase plane tickets for us to fly home since BMW couldn't remake a key for 3 days. We agreed until they offered another car at the same price. A BMW 325CI convertible. We fell in love with the car and agreed to the purchase. We traded the car a year later and found out TEXAS AUTO DIRECT had sold us a car that had been wrecked and it was not disclosed. After several messages to the general manager, we are still waiting on a return call. We lost almost $5, 000 on the car since it had been wrecked! They run a SCAM!
