Well I probably wouldnt be looking to buy until spring time more than likely but if I was going to get a cobra I wouldnt want to spend anymore than 19k or so. Once I get around 20k thats Z06 territory and if Im going to spend that much Id rather have the vette. Plus Id have to get financing which is a bitch for a private sale.
Id probably only get 7k-8k for my mustang as well so Id probably want to save up another 2-3k so I dont have to finance too much money, not a big fan of being in an assload of debt.
