That's working both ways.

A LOT of them have been leaving Japan lately. They were prestige items over there when new. Many were driven very low mileage and put away.
Quite a few were left hand drive euro-spec cars, and some of them were even US specification left hand drive cars.

A lot of them are being imported into Canada now, as the regulations really become relaxed for 15 year and older cars. Since the last W126ers were '91s, that makes all of them fair game for export from Japan to Canada.

Bruce Mendel, a forum member here, and a self admitted W126 fanatic has connections in Japan, and has been able to bring in some of them in, and knows the process very well.

He finds the really good cars, and brings them here, and resells them. He has his own client list. He's a VERY knowedgeable individual, reputable, fair and REALLY knows these cars.

In the last post at the bottom of the link below, he describes a few Japanese ones he'd imported,
one of them being a 6.0 ltr 560SEL AMG from Japan....
