I am a simple person (so my wife confirms for me)
GT-R34 NSpec with full aftermarket engine enhancements.
MB G65 4x4
Rolls Royce Phantom for evenings out and touring.
GT 350 Mustang Fastback
AeroMax
1963 Riva Aquarama enhanced wooden dingy.
I cannot possibly use any more than this.
If I do gain omnipotence I would play the wild card and reserve the right to swap my toys at any time. Except the AeroMax.
