If a Citroen, rather a C5 than a C4. Yes, all cars in this size are cheaper in the UK than here, but at the time I prefer Vauxhall, because this is even a different, here no common brand. Sure, it's everything identical with the Opel's, except grille and badges, but it's a bit more unique than a RHD Peugeot, Passat or so. Faked Vauxhalls aren't rare, too. Some boy-racers like to put the badges on their Corsa B or Vectra A.

Sorry, the Amarok is far our of question. Except the fact, that I'm not interested in any SUV (the towing capacity, I need, is possible be upper mid-size-cars anyways), for sure I would never spend that much money for an all-day-car:

For roundabout 20.000 € and the help of the M100-club-president (I know him a bit), it's possible to get a http://suchen.mobile.de/fahrzeuge/showDetails.html?id=141444953&__lp=7&scopeId=C- &sortOption.sortBy=price.consumerGrossEuro&sortOption.sortOrder=ASCENDING&makeModelVariant1.- makeId=17200&makeModelVariant1.modelId=136&maxFirstRegistrationDate=1975-12-31&negativeFeatures=EXPORT&lang=de&pageNumber=2
So where shall be the reason to throw away money for a useless SUV (even it's Argentinian made ) when you can get a real dream-classic?
