For me it is an investment, like shares or bonds.
Sometime back some one told me that the most expensive HW car is a VW bus with a surf board suck in behind.
Just found out one of the owner is Bruce Pascal. If you have an extra $150K USD laying around, you can own it.
To know some background on the pink Rear Loading Beach Bomb owned by Bruce Pascal.
