i think there are 2 to 3 main problems with american style cars in europe.
1) price.
http://www.focus.de/auto/fahrberichte/t ... 59603.html corvette C6 US:~45k $ => 35k €; Germany: 60k € nearly doubling the price with taxes and shipping? i dont think so.
1b) taxes: not only on buying the car, but ongoing eg.: fuel. 1l (~ 1/4 galleon) costs 1.3x € in austria, so a 100l (read somewhere thats 26.4 galleons) tank equals 130 to 140 € => (130 * 1.2) ~ 156 $, and americans cars have at least the image of gas guzzlers.
2) enviroment space: i know 3 parkgarages in vienna where a Q7 cant enter without damage, be that the roof upon entering or the wheels ( and probably something connected to them with the 25 cm curbs) in the up and down spiral. in the rest you need 2 lots because with a single lot 90% of the time u cant enter it anyway, and the rest means u cant open the door...
so 5x2x2m (l/w/h) cars are more or less beyond the max. acceptable size and a pickup fitting those still has the problem of space usage. what do you need a dedicated, non weather proof transport area of such a size? a tourer (hope thats the right word) has more or less the same space, maybe with folding the backseats, but weatherproof, and u can leave stuff in there and its not out for grabs.
3) technological/feel image: i can only write for austria and germany, but here the image for blatantly american cars (opel is mostly still seen as seperate entitiy to GM and Chevy) is low tech, comparable power only with more engine volume, therefore wasting fuel, bad handling through corners mostly due to the low tech suspension, wasting space, too big, and also wasting engine power with low tech transmission. and sport cars with automatic? (im not talking about mercedes AMGs, many dont see those as sport cars, but tuned luxury cars) till recently a big no-no, and even now the german car industry takes many pains to avoid calling CVTs and double clutches automatic, even the classic automatics dont get called that. also again american automatic with 4 or 5 gears? low tech, mercedes has 6 or 7.
i admit the above is an exaggeration, but nonetheless u cant exaggerate feelings that arent there.
the media isnt quite innocent (more the opposite, as usual

). if one reads the auto, motor & sport, in nearly every article about german cars theres a quarter of an A4 (most of the time more) page just about new tech implementions. eg: new engine in an audi/bmw/merc listing of the new features, praising them above the old ones, the picture of a cut-through pointing them out, then talking about how good they feel when driving.
corvette: new engine, and again more volume, great sound, BUT cheap looking interior materials, at best medicore handling/automatic etc.
and the above magazine is quite a big player.
