Hey Scotty you always talk about how new GM vehicles are junk and how good the old ones used to be, so when was the last good years (or years) of GM?
If you're talking about the time when GM led the industry in design and engineering it would be probably around 1970. During the 1970s the company started dropping the ball quite a bit meeting the challenges of emissions and safety regulations and the onslaught of Japanese competition. (As far as at least having a decent level of reliability you'd be talking about GM vehicles built pre-bankruptcy and you need to be selective.)
Probably 20 yrs ago..
You have to go all the way back to 2006 (give or take 1 year), before the era of cylinder deactivation. Now their heavy duty trucks (2500+ HD) are the only decent products they still make.
The charts say it all
