Im afraid the only real incentive would be to make it mandatory to own the other cars (and imagine the storm that will cause..), ie. having showcases and TTs for every car (just like career).

However... in an utopian world.. Id suggest giving a discount on every other car you accuire in that serie., ie 750gc for the first, 500 for the next, 300 for the third ,etc.
