My old man worked for Allison in 1940-41 and never thought much of GM. They were tyrannical and didn't care about safety issues. He told me years ago he'd never buy a GM car -- he considered one once (a 1966 Corvair) but ended up going with a Plymouth -- he had a family to haul.
He was as good as his word, he died with a Plymouth and a VW in the driveway.
He always said that GM's problem was, they weren't a car company -- they were just a bunch of bankers who owned a car business, and didn't care about the product.
I had a total of three GM company cars in the 1980's after he died, and boy howdy, was he ever right. They sucked big, big time.
I bought a brand new '96 Chevy Cavalier--and it was an unsafe POS. The clutch kept going out. After the fourth time in 2 years--and getting nothing but a run-around from Chevy's "customer disservice" department--I bought a Toyota.
I vowed that GM would never get another penny from me. And now the federal government makes me give money to GM and its Union masters.
You will need a loaded gun to get me out of my Toyota.
