The same goes with a skyline driver, only less midlife/girl and more 'backwards cap wearing, wacko, doof doof hoon'
I wouldn't be too sure on that one, look at the values of 33 gtst's now, as compared to what they were five to six years ago. 34's will go the same way. In that timeframe a Z will still have a lot of value on it.
Go the Z imo, 34's are tough, but it's not a match for a Z. Good performance from stock, it'll still hold value, and it will give you the peace of mind you'll never get from an import (genuine k's, service history, you can take it to ANY nissan dealer and get it serviced, rather than having to go to a select few workshops in major cities). Not to mention, they have a bit of menace about them to begin with.
