"My Uncle bought a LJ torana in the late 60's for about $2000 and 5 years later it was worth $500.
Its now worth about $20,000.....mint condition.....I bet people were calling him a mug for keeping it at the time....seeing the value drop so quickly."
Using the RBA inflation calculator http://www.rba.gov.au/calculator/calc.go
The $2000 dollar car would cost the equivelant of $20039.51 in todays dollars. This assumes buying it in 1968 and selling it in 2008.
So your uncle has actually lost $39.51.
I hold property and expect prices to pick up end 09.
