Congrats! The GSR is a fun, economical and practical car all at the same time.
I'm the original owner of a two-door 1998 GSR (w/ leather) and I love it. For the past three years I've been saying that I'll sell it since I hardly drive it, but I can't bring myself to do it. :biggrin:
It doesn't need many or any mods to be fun - just use good tires (Goodyear GS-D3, S03 (while you can get them), RE050, etc) with the stock wheels and it will be fun to drive (budget performance tires really suck on the GSR - I've tried them).
Now, thinking back, I wish I would have picked up 4-door GSR - same fun, but even more practical. :smile:
