I agree about the non turbo comment! Good work! I started with an s13 q's.. 92 model manual, immaculate!
But lets not kid ourselves, in stock form they are BOTH f*cken ugly cars. The r32 is slightly heavier and has less 'dorifto' handling characteristics. Your far more likely to slide around like crazy in the wet in the s13.. its hell fun but pretty manageable.
The s13 looks shit hot if you dewing/debadge and drop it.
Same with the r32.
Edit: Just FYI, if your going the s13 get the SR20 engine. (ie get the latest model you can afford) .. also, they are a bit of a bugger to sell so make sure you offer the guy 2 grand less than what he's asking and bargain in from there.
Then with the spare charge, invest it, dont spend a cent on your car, drive it for a year or two then upgrade to something turbo.
Good luck!
