I believe the 124.133 was available in the rest of the world through the end of W124 production in 1995, including Canada, eh. But it might have been an import to Canada. Might be able to tell more from the VIN. I like the dual zone climate control. It has a front-end facelift, probably had been in an accident at some point. I think it has factory EGR, unless that actuator is for the flapper valve - can't quite tell from the photo. I don't like the lack of airbag, and vinyl steering wheel.
BTW - pretty much all diesel models have the vented fender, worldwide, except for the USA-spec 1987 300D. Go figure! I never did understand why they did that.
