Forget that people - no where on earth will you have 2000 cars. Just think about it for a second, if one car is modeled in just one day, you can count about 2000 days to model all of then. One possibility is that every 2nd car\'s model is re-used, but what would you do with that many anyway? I\'d rather have fewer cars but a broader range to choose of. We don\'t need 2nd hand cars...
2000 cars and 100 tracks is a bit too ambigious...
