There is a significant scalp market for the limited release Porsche and other premium cars in the UK. Its not uncommon to double your money on some cars just for sitting in the queue for the car for 12 months or so from using a small deposit of say £5k.

Hard part is getting on the list to buy one, you need to be in good standing with the dealer from purchasing a lot of cars, which most scalpers are. You can then sell the place on the waiting list, or finance the car, run it for a short period if you want, then sell it for a big profit.
