Mine is 4.40 m:


But if I keep few cm for the door, there is 4.30 m left. But that supposes that I park close to the wall, which is not easy without hitting the wall So a car that is 4m (like the 206sw that I currently use) - or less - is easier.
But as I do not close the door currently (as there is nothing else than the car, and as it is a garage inside the underground of the building where is my apartment), I could put a longer car.

You say "your garages", you mean in Belgium/Europe ? That depends on the garages. One of my colleague has enough room in his garage to put his Audi A6 + the Peugeot 406 of his wife


I do not like the 607, but I'd like a C6 if I had to drive only on highways (i.e. not in city like what I usually do :D)
