yer this is most likely turning into another series bashing thread (old vs whale vs pricey)
The inside of the car is where you spend 100% of your time whilst driving it! So, the newer the better I say!! Unless you are an 'U'ber track-master, where an extra 50kg's is actually going to make a difference, they shouldnt be much more to it than that.
so therefore, the only real debate that remains.. is the 'looks'. but this is like debating people's favourite colour!!! Everyone is going to have a different opinion on this, but I think that the GTS-T's/GT-T's are a particluarly boring car in stock form. all it takes is a bit of imagination and modification, to make people to stop and say "WOW!". you can do that with just about any car!
personally, i think that the RZ supras are a MUCH better looking car then the 'lines in stock form.. they have that 'sports car' look! As for excitement, i think that the 'lines take it, just for the performace.. i used to have a supra, and they are predictably sloppy compared to the skyline. I have a lot more fun in the line than i did with the supra...
anyway thats my 2c
