I remember in automotive technology class the instructor recommended
that if you were going to work in a dealership, Saturn would be the
one...the reason, among others, being that there are a relatively few
different models, versus working in a Dodge, GM, etc, each of which have
a myriad of different model cars, trucks, etc.
So in buying one, and having to have it repaired at the dealer, you'd
have a considerably higher likelihood of having it repaired correctly
the first time.
Nothing wrong with a GM, though :-))
