An irish guy done similar only it was £100 a ticket for 75 people...on a impreza type r 2dr with 450bhp. Lota of photos, docs and half his payments was going to a charity. Then he wrote down name and locations of the ticket buyers and then chose a number between 1-75 and the number related to a buyer...so 4th ticket buyer got ticket 4, and so on. Then he posted a photo of him and the winner, then a photo of him handing a cheque to some sort of cancer charity.
Was as odd as a ginger stud with two left feet, but he got rid of his car, got some coin and give to charity as promised!!
