I read in another topic that putting Liberty city in the game would make a major problem with game preformance and there would be many issues.
If someone did that, hopefully they can make most of the original cars, if not all, plus the bikes in VC and some modern helicopters.
0.2.2 has many crashes filter out. As long as no one on the server cheats, and they destroy any vehicle they are abandoning, everything will be fine.
