I just bought a 2001 Spa Yellow s2000 and I am completely happy with it...except for that plastic rear window. Is it possible to just have a glass window put in? Or would I have to have a whole new top installed from the 2002+ models?

 

you can't just replace the windows, you have to buy the 2002+ softtop w/ glass window which is about $800+ brand new from a dealer. to make the new softtop fit you have to modify the frame of you 2001.

you can also switch in the whole assembly from a 2002+ s2000 [frame+softtop], but its the more expesive route to go

if you look in the library section on this site, a member did a write up on how to do the installation yourself at home...also try a search on "retro fit" and you'll see many threads about this topic
