They are very well built, just be mindful that they're still 20ish years old now but mine still runs brilliantly.
I had a comment from a chap in work the other day because I pulled into a parking space and got out and left the engine running and he was amazed at how quiet it was, he thought I'd turned the engine off until I came back a few seconds later, jumped straight in and drove off!
I'd always fancied a supra or a skyline but the rusting issues kinda put me off the skyline, a mate has an r32 gtr and its pretty much a rust bucket, perfect from the outside but if you look underneath the chassis is pretty much rotten
