i can think of the following way they want to avoid

person fully upgrades a car, does all the races possible to gain more progress in the game, than somehow that car is missing from the garage, than giving gold back is same as having rented the upgrades :)

+ if they give a fully upgraded car, we cant profit extra from future discounts for that car
