Because the whole car list is 500+ cars, and some of them have already been done, and others I don't want at all.
I posted this to give modders ideas, specifically that some of the older cars need to get done instead of the constant focus on cars made after 2000 that were either already in TDU, or are just the next year's versions of TDU's defaults.
The Aston Martin DB5, this rightfully should've been in TDU by default, it's James Bond's first gadget filled car.
The 959 should've been on someone's project list by now, that's been a most wanted car for a very long time and it's one of those "mythical" cars that everyone wanted, but could never have.
To date, nobody has done a decent "HachiRoku" AE86, they've all had various problems, or worse, loaded down with bodykits and wings and carbon fiber everywhere.
The Toyota 2000GT, another Bond car, it was in "You Only Live Twice", though not Bond's own car in that movie. It would make a perfect replacement for the Jag E-Type, or a perfect replacement to race against it with similar physics.
Also, it's just a huge waste of time for modders to all do the same cars, there's no reason for it really. The only reason it's being done right now is a lame competition with each one silently saying "I can do better than you can", and it's childish to say the least. If all the modders were working from the exact same information, I guarantee that nobody would be "on top", the playing field would be drastically evened out.
