Here's a clean example of a R34 GT-R non v-spec in bayside blue with genuine low km's which sold for 3,655,000yen which is about $41,000AUS.

By the time it is landed, complied, new tyres and service (compliance rules), registered and other little things, this clean GT-R would owe you about $52,000AUS roughly. So people clearly need to understand that these cars are becoming rare to find in this condition, but not only that, they are also actually hold value and appreciating rather then depreciating. You can buy a R35 GT-R in japan for the price of R34 GT-R's in japan now.
