NFS World: Vehicles Without Roofs!

Need for Speed World have so far released 5 vehicles which are convertables. This basically means more graphically detail and being able to see the driver. It's interesting to note that they've been doing this for almost 2 months now. Compared that to something like Drift City where they've released the same amount of vehicles within a 2 years period. I think EA are really trying hard to make more. If that's the case, I want to see a Pontiac GTO without it's rooftop.
