with a post by gabster saying parts will be changeable after a search i couldn't find anything on the topic, anyway i thought we could have a mode like this http://www.youtube.com/watch?v=l3R2oJGAzKg
not sure about fully customizable but i would like 3 or more options per vehicle. (engine size, offroad, racing, etc)
I know that I could be asking a little too much here, but a modifier that could be used to create cars like seen on top gear would be rather fun... But I would also like a garage with all of the basics too.
