you gotta realize that there are some awesome supras out there - most are owned by kids though, and these kids rice the NA's up heaps. Personally, I dont mind either of the twin turbos (supras or gtrs). GTRS will def be practical. and yeah for 25 g, you can get a 95 (maybe 96 gtr if its being imported from japan). for 25 grand you can get a 93 or 94 supra twin turbo (so about a year old) - however I did see a 97 blue supra twin turbo on j-spec just recently.
In my opinion, if your going for a supra go the 96+ model as they are updates. Same with the skyline - 96+. If you are only going to use it as a road car, get an NA supra or a r33 gtst series 2 (imho). But remember, as i always tell people, these cars are more at home on the track - so be careful with the right foot....
