Mine is a 1992 too, i have had it close to 2 years now, i purchased it before that stupid 15 year rule come in, so there wasnt that many ones out there to choose from.
Yea i have kept mine standard if i wanted to mod a car would have got a wrx or gtst!
Im not in a hurry to sell but am looking to buy a property and having 2 cars is a bit of a hassle at times.
With youre plates definetly desirable for a GTR just have to wait till you get the right buyer.
