i'd buy the block of land next door and excvate it down to the level of mine. Build an underground 20x25m garage (drive in from the level of my place) and build a house on top of it to rent.

Then buy:

1969 ZL1 Camaro.
1970 Z28 Camaro.
426 Hemi Dodge Charger.
XA RPO83 Falcon coupe.
LH L34.
1971 HG GTS350M with McKinnon engine.
HQ Kingswood Sandman ute.
Get my yellow GTS327 finished with anniversary ZL1 engine.

I'd also like to do something charity wise, not just donate but set up a foundation of sorts.
