Quaking,
I know the GTR's you are looking at.
The blue one has heaps of gauges- screwed directly in to the dash! Probably been boosted heaps too… Personally, I don’t trust it a boosed GTR can cause problems.
The Gray one has accident damage- ask evo, they sold the car to the previous owner, who has damaged the front right panel.
Don't believe me: open and close the bonnet of the blue one... then open and close the bonnet of the grey you may find a difference- well I did.
My advice to you in your current situation: Get the GTS-t or just stick with the 180sx. GTS-t are “common” these days in Canberra but offer excellent value for money. 180sx not so “common” and offer great value for money.
GTR is best for after you have paid off the house.
Money is in your hands- you decide what to do with it!
