Most UNRELIABLE..... Anything made by General Motors.... I've owned very few GM products and been issued several GM products as company vehicles... EVERY one in its own way stranded me multiple times.. Not IF it would fail, but WHEN and how often it would fail... My 5 cents of experience with that..
My most memorable personal vehicles were a 62-63 (?) Mercury Metior, a 70 Ford Maverick, a 75 Plymouth Duster... These all owned as a single guy and involved in a number of ....adventures....
