I was in this situation, was looking at liners, rx's, supras and scoobs...
Scoobs i found boring, and a bit too common,
Rx's were a bit too bad on fuel/oil.rebuilds
So that left the liner/supra.
Insurance on a GTS (which would have been slower than the sx ive just sold) £1000 Add to this nissan are rust magnets, and its a bit of an expensive tin can!
For the same money, ive bought a nice TT supra, and insure it for about half the cost.
Depends what your priorities are, i was slighty aggrived by being charged loopy insurance for a car just because it has SKYLINE written on the boot. (that and i love supras, justs didnt realise i could actually afford one )
