The prices would naturally reflect that... players who have rare cars would want to sell them for a high price.
The question is tho....How can we get cars.....Currently, cars are spawned through spawn menu for free... If the game becomes something like SLRR, will modded cars be avalible for use and for sell?
Well... I would assume that every car would be bought brand new to begin with then...? And then some would just be given as rewards for completing a large mission, or you may just get a hand me down from someone when you complete a series of missions or something along those lines. Pink slips? Hehe
