I seem to have an affliction. I get these perfectly excellent cars, own them for a year or two, and then get bored and start suffering from a little of the "grass is greener" deal. In this case, its basically redoing a car i already did once, just with more motor and an IRS. I really did like that mustang.
Though you folks are of course right. Ill hang onto the Z for now, just time to do a few things to it. have some fun brake stuff on the way already.
