Ok, so it's not a Top Gear UK vehice, which would be freaking awesome, but it IS a Top Gear vehicle. The modified '73 International Harvester Scout II Rut drove on the trip is on eBay right now. THe price is currently sitting at $9800, with 3 days left on the auction. A steep price, even with the modifications, and then there's the fact you'd have to get it herr from Iceland, where it is still living.
Damn nice looking though.
