The eariler models, it WAS a merc engine, in the later ones the engine was
built by SY in Korea under licence from MB, which is why a lot (not all) of
MB 602 parts drop straight in, so perhaps you are right, the engine was not
built in germany, so not MB, but it was built to MB spec and design, and is
badged MB on the engine, so that makes it MB to me, not that I care, I drive
a car with a silly badge that nobody can pronounce and that didn't cost too
much, it drives well, runs on any fuel I throw at it, pulls my large caravan
with ease, I don't struggle for any parts, and when I want to play the car
copes admirably
