Big diffference between a Hummer and a '70 Electra!
I too am utterly delighted that Hummer production will cease. They're a menace in traffic because they block everyone else's vision, and trying to get around a parallel parked Hummer can be downright dangerous on a narrow hillside road since they're so wide. Outside of military use, there is very little reason to have a Hummer. Creating oversized and inefficient vehicles is not a good endevor, but keeping old cars on the road is very different.
If your preference in old cars is American luxury cars made between '70 and the mid '80s then all I can say is you're in luck as these cars don't usually bring a lot of money. Most collectors lose interest very quickly after the 1970 model year as build quality went down for all American manufacturers. Lots more plastic was used in both the interiors and exterior (between bumpers and fenders, for instance). Padded vinyl tops became popular and these promoted rust problems, while the plastics don't age well. The basic mechanical stuff was still pretty good, but emission controls like smog pumps and manifolds often changed from year to year and is now impossible or difficult to get. That's OK if you just want to drive the car and don't live in an area where you have smog checks, but if you do have smog checks or want to restore a car to truly original condition it's a problem. For these reasons it's much more difficult to restore a car of this era than one made during the '50s or '60s, and the result is generally worth less, hence the lack of interest.
A buddy of mine had a '70 Electra convertible several years ago. It was a really nice car, white with a white top and red interior, very pretty. One summer we went up to the Great Autos meet in San Luis Obispo. We took I-5 over the Grapvine, which has a significant grade and is a famous car killer in the summer. I was in a '73 DeTomaso Pantera, which wasn't known for having an oversized radiator, to put it kindly. I wasn't quite sure how it was going to handle the Grapevine in summer, so crossed my fingers and asked my buddy to follow me in case it overheated. Imagine my surprise when the Pantera sailed up the hill with no problem at all, but when I glanced in the rear view mirror I saw the Electra blow a hose in a cloud of steam. The end result was the poor thing had to be towed back to LA, while we both continued to the show in the Pantera while cracking jokes about it being the "rescue vehicle" - thankfully Panteras have both front and rear trunks so all the luggage fit after some squeezing. The Electra was repaired and went back to its usual duties of wafting elegantly around Silverlake.
