I have owned or the family has owned about all of them....there is some things I hated about all of them and some things I loved about them all too.
Personally I grew up in a pretty much GM family and have had great experiences with most we had...one was a 73 Chevy cargo van that got used and abused every day of its life still ran strong with 479,000. miles on it when I sold it.(no it was not a diesel)
