having owned 2 BMW's, I must say they are OUTSTANDING cars.
however, (and this is true of all those makes you mention), they are going to BREAK YOU at the dealership. There's a reason 3 to 5 year old Europeon cars are cheap. All that little cool stuff breaks down, all the time and it just nickels and dimes you to death.
don't do it.
if you want a europeon car, buy (or better lease) a new one with warranty.
and stay way the hell away from VW, major reliability problems since the late 90's.
