gtrs can be a money drain very easily, fixing or replacing things can cost an arm or a leg.. i'd choose very carefullly, if u go with gtr, hope u handy with spanner as it helps being able to do as much yourself.. also no guarantee r33 motor wont blow up like a r32 so factor in a stash of cash to keep on reserve.. all the best
p.s in regards to insurance, im with shannons, u can opt for the weekend only (limited use) which reduces the premier by a fair bit, otherwise $2k odd in insurance p.a
