There are plenty of Contours in the UK... go near a US installation! Bet you'll see a few... RAF Lakenheath and RAF Mildenhall come to mind.
However, it's easier to bring imports into Europe. VAT and converting to Euro spec is going to suck, though.
Not sure if you know, but all US military in the UK have to convert their vehicles to meet Euro specifications (not the case here in Germany), so I know a bit about what it takes.
Things that need converted on a Contour:
• Rear turn signals - Contours have integrated brake/turn signals.
• Rear fog light - Most US spec cars do not have this
• Side repeaters - Again, most US spec cars do not have these
• City lights - US spec cars do not have these (some older Japanese cars do)
• Headlight aim - Must aim them the opposite direction
• Reflectors - Seems that rear reflectors near headlight level are required
• Headlight height adjustors - Required in Germany, not sure about the UK
A German civilian in my shop went through a divorce from his US military wife and could no longer use the USAREUR registration on his US spec Focus hatch, so he had to convert it to Euro spec (like above, but minus the headlight aim, obviously).
Since a US Spec Focus is identical to the Contour in issues, he had to do the following:
1. He had to cut the turn signal wires and run his own to the back of the car where he installed yellow lamps in the old reverse light hole. Since US spec cars flash one of the brake lights when you use the turn signal, running your own wires bypasses that and brings it into complaince which says that you MUST have yellow turn signals on the rear.
2. He had to install a rear fog light below the bumper, just like you see on older vehicles since there isn't even a spot for a fog light on US cars.
3. Since he used the old reverse light spots for the turn signals, he had to install a new reverse lamp, which is also mounted below the bumper on the opposite side as the fog lamp.
4. Had to install side repeaters on the front fenders and wire them into the turn signals using resistors so the turn signals don't freak out and flash fast.
5. Had to cut the existing parking light wires on the front turn signals (our front position lights are yellow and integrated into the turn signal) and run them to white lamps installed in the grille for city lights.
6. He had to install some stick on reflectors on the bumper, most likely because the rear reflectors on his Focus are way up near the roof (where the brake lights are).
7. He had to obtain a waiver letter from the TUV since his car does not have adjustable headlights from the inside of the car. Not sure if UK spec cars have them, but there is a 4 position switch inside German spec cars that raise and lower the headlight aim (usually accomplished with engine vacuum or a small electric motor) to compensate for load, etc. NO US spec cars have this feature.
OH, and BTW, I'll sell you mine for 2000£, but you'll have to convert it to UK spec... also you will more than likely have to spend a lot of money to register it, since it has TONS of aftermarket parts... I'm located in Germany, btw, so shipping will be cheaper! Hell, I'll even drive it there after I fix the idle and get it to pass inspection here!
If you were to be interested, I could possibly do some of the work on converting to Euro spec... Already has side repeaters, and I can do the other wiring stuff like putting yellow lamps in the reverse socket, and install a fog lamp and reverse lamp similar to what the dude did on his Focus (but would look better, since I can put it behind the mesh on the cutout). Headlight aiming will suck, and probly have to be done by a shop up there (heard they will even put TAPE on the headlights to block glare from oncoming drivers).
