Koons Tysons Chevy Buick GMC

After 5 months of searching, this weekend we cam across a good deal for a 1998 vert will all the options that we wanted (6spd, HUD, ect). I contacted one of the salesmen and he send me an email with there in good deal for a 1998 vert will all the options that we wanted (6spd, HUD, ect). I contacted one of the salesmen and he send me an email with there internet price. I talked with the salesman over the phone, checked the carfax, agreed on shipping through the dealer and agreed to buy the car at the advertised price. He said he would call me back to set up financing, when 5 minutes later the sales manager called back and said that the price is now $2000 higher then what was agreed because they have been getting so much interest in the car. I argued with the sales manger for 5 minutes and then he hung up on me. I have been treated bad by car dealers before but I have never had one try to blatantly jack up the price $2000! More
