Yep, at 72 I've seen a lot of those old ones. Some were funny, some were entertaining, some contained some great info. Now, I very seldom watch tv. (Actually about a 3rd of my time is spent here on TNet!)
The vehicles today have too much on them to try to tell the viewers about. So many electronics, so much cheap trim that costs a fortune, and for looks----there have been very few vehicles on the market during the last few years, that I would call decent looking. I don't like the styles. I guess I haven't evolved enough to think of the newer models as 'pretty' or 'eye candy'.
I've repaired a lot of the older models. Until a few years ago, I repaired my own vehicles and very seldom took one to a mechanic. Now, I am just not physically able to do much. I believe the last time I overhauled an engine was in 2005. I had a small Jeep Cherokee with a bad crankshaft and some of the seals in the tranny were leaking. I pulled the tranny to reseal it, and while I had it out, I replaced the crank, and overhauled the engine. Even had to replace all of the seals in the fuel injectors. It was an old 1989 model. Wish I'd kept it. I sold it before leaving Texas in 2007.
Remember the hex wrench to set the points on GM distributors? Turn the wrench clockwise until the engine missed, then back it off a bit. Don't remember how much, maybe half or 3/4 turn? 'Course there were the flexible tools for setting the points instead of the hex wrench. You were supposed to check the dwell after setting the points, but not many did, except professional mechanics.
