If money wasn't a factor I would buy a garage and stuff it with a lot of decently priced cars to mod the **** out of.
Holden Ute
86 Grand Prix 2+2
The Petty edition GP
Intimidator SS Monte Carlo
2012 Camaro ZL1 Synergy Green
Mclaren Turbo GP
Silverado SS 454
65 Camaro
80 Malibu
DMC Delorean
and probably a Gallardo, just because I want to take one to a demolition derby.
