I find a few things on my car are a little aged, no its not a GTR but the same things could happen. like:
Dash lights like the rear demister switch, hazards etc dont work
Climate Control lights dont work except for screen
There is an issue with the climate control somewhere in that I cannot move where the air comes out - its always face level
Needs a new A/C comp
Rubber seal around back window sunburnt a bit
Steering wheel could use some new hide
nothing major, just what you would expect out of a 16y/o car I guess. All could be fixed, I will get around to it
mechanically, it purrs! *touchwood* haha
and something I am particulary fond of: NO bubbly dash
