>>>I don't understand what you mean by "reservation class". I know it was a station wagon. Funny thing I always wonder if I should save these or those documents after vacations. And usually, after keeping them a few months, I discard them. Now I know of a case where keeping the rental papers would be helpful :)

>In the language of American natives, the "station wagon" is what you call "karavan" - which also makes no sense, as there are no camels or horses hauling the merchandise from city to city. What they call a van (abbreviated "caravan") is what you'd call "kombi". Your coupé is called hatchback; your cabriolet is called convertible (as if it was a currency). What you call limousine is what they call a sedan (etymology unknown), and what they call a limousine is one of those long jobs with 6m between axles and a luxury salon in between, swimming pool and golf course optional.

A caravan is something what the second most hated group on a camping ground is using. They are normaly slow (less power due to tax / insurance regulations) as the animals you mention and sway, so I see a similarity. Station wagon ends up with a simple Kombi. In general I don't care about marketing and use a car. :)
