No. I don't think you do. If you go buy that new car (the upgraded one), is the new car vastly lower price than you old car was...No. It's your old car that's depreciated as compared to the new upgraded version. Bungie has it the other way around. They've got the all new next year model with all the upgrades included, priced lower than the last years model was, and they're including last years model as a free included bonus as well. You nearly get two cars for half the price of the original car upgraded cost.
