We spent from 1990 to 1998 in Germany with 2 cars, one RHD Alfa 33 and one LHD Mercedes E Class. Then on returning in 1999 we had a LHD Mercedes E 200 and a RHD Alfa 156.
The only real issue are car parks, but you learn to just get out. Otherwise it isn't a real problem.
Only a couple of times I went out to a car, unlocked the door and got in, only to find the wheel wasn't in front of me.
IF I could get a LHD Aeromax in Europe for 30% less than the UK price for a RHD then T'd be very tempted....
