Most Expensive Car: This is the world’s most expensive model car. The Bugatti Veyron Diamond is on sale for two million pounds – twice as much as the real thing. Liverpool-based designer Stuart Hughes took two months to create the intricate 1:18 scale model in partnership with Swiss luxury model car maker Robert Gulpen. Weighing in at 7kg, it has been created with platinum, solid 24ct gold, & a 7.2ct single cut flawless diamond on its front grill and is 10 inch long. Actually I think I'll pass!
