Great fun, slightly frustrated

I love this game. I cant say why exactly, but there is one frustration. While cashing in dollars, and lucking out to get rare or epic...I get many doubles and that whole 100 is wasted. Why not have a "garage" and trade in program? 3 epics for 1 choice of epic. 10 rare doubles for 1 epic. Who cares...just feel that if the cars are worth $4 each, I shouldnt be getting so many doubles.
