There now over 100 vehicles in Need for Speed World.
I actually don't care now because you're not going to find 100 vehicles to explore in the dealership as some of the vehicles have been retired or are already kitted up without no stock version for sale. Interestingly enough it's working as the game has also clocked over 7 million players.
However this is the kind of MMO that I would want because of the mixture of scenes in the game when you do see a vehicle which isn't really in the dealership hence making it a good MMO. Just need more events and task to do.
