I wonder how many of the big GM wagons wound up meeting an early demise due to the "Cash for Clunkers" program. There just don't seem to be as many of them lurking in carports and back yard garages as previous generations of cars did.
I recall back to being a kid in the 80's, and there were 70's/60's vehicles everywhere. As time went on they weren't as proliferous on the roads, but it seemed like every single neighborhood had 60's/70's, sometimes even 50's cars and trucks sprinkled everywhere. But the 90's cars seem to have vanished almost completely.
