This game could be _really_ great, but from my point of view there are a few things that keep it back:
- yes, introduce the "sell"-option... in fact, rework the whole system of buying cars. As it is now, after half of the missions you have all the cars and then this whole mechanic does not matter for the game anymore
- concentrate more on the "car-stunts". I saw several ramps for jumps in the city-map, why are they not used in the missions?
- maybe give a little more guidance on which way to take to the target? The way it is now it's a bit cumbersome to find the way, also because the cars are so slow.
