Lottery draws on cars and bikes are held at the airport on a regular basis. The company in charge of this business calls them competitions but it’s pure luck. There are usually Porsches, Audis and Range Rovers to be won but this is by far the hottest car they’ve displayed.
There are 2400 tickets @ $135 / ticket.
Now the part they don’t tell you:
When you win the car, you still have to pay the customs duty. So in case you win the Aston Martin you better have 60 or 70K in your bank account if you want to drive it on the road. Apparently what happens is that when it is won, the winner is approached by brokers who try to convince him/her to sell the car at a cheaper price.
