This is a mod I have been working on for the past few years to bring NFS III up to modern standards. I have currently abandoned work on the mod for NFS III due to difficulty of working with the engine eg. texture sizes are limited to 256x256, cars are limited to 10000 poly's etc. ! Currently I am porting most of the work i did to the more advanced NFS 4 game Engine and it is looking promising already. 
Hera are a few screenshots of the replacement car select menu I created for the need for speed III mod i was working on
A screenshot of my partially completed home town revisited track
(The original hometown track remodelled and retextured)
screenshots of my NFS III car select showroom running on the more advanced NFS 4 Game Engine. Busy converting my entire nfs III mod to NFS 4
I also posted this in the gaming section.
