That's not an "old truck"! It's a rare, classic truck restoration. The only reason to buy something that old would parallel the reasoning of people who collect $20,000 pocket watches. Unless you have the resources to resurrect and maintain an ancient vehicle like that, you wouldn't want the headache of finding parts (if there are any), or even getting the right mechanic to do the work if you don't do it yourself.
I have an "old truck". That is -- it is my brother's old truck, and he can't drive a 5-speed manual much anymore because he's at risk of having his left leg amputated. It's a 1995 Nissan "hardbody" King Cab pickup. It's black, and it spent at least its first 100,000 miles in the neighborhood of Trona, California, leaving the paint very well -- or badly -- oxidized. I fixed that problem last year. In fact -- there was a lot of surface rust on the cab top, and spots appearing on the hood. The rust seemed so bad, one might worry that it would require metal-panel replacement -- serious body work. You could run your hand over the surface and than see little piles of orange dust on your palm. I ground it all down to bare metal, used two different chemical treatments, and more sanding and reapplication until the chemicals didn't turn black anymore. Then, two coats of epoxy-primer, followed by the factory black acrylic enamel and clear-coat. No . . . more . . . freaking . . . RUST!
It was a mechanic's special -- mechanic owned and driven. It has 170,000 miles on the odometer, doesn't lose or use a drop of oil. It is excellently maintained. And the only reason anyone would want to buy it: it is 4WD. We've restored everything from missing OEM sun-visors to molded vinyl door-panel damage -- chunks of vinyl and foam rubber missing from the door-handle, etc. Cracks in the dashboard as well. One of the rear push-out windows had a damaged seal or grommet, which required sculpting with silicone RTV sealant-adhesive -- and it looks pristine now. I really need to get out and drive it around -- hasn't been driven in a month or more.
I'm still debating whether to spend a few hundred on chrome-wheel replacements for the OEM originals. If we were planning to sell it soon, I don't think that would be a good idea. It sure would look nice, though!
I DO need to get out my digi-camera -- or cell-phone (but I prefer the camera) -- so I can post color pictures of the Nissan Truck and my fabled 95 Isuzu Trooper.
I assume that your expectations for this thread would anticipate a lot of "show and tell" responses. And -- is an SUV a "truck"? Standard SUVs are supposed to be built like trucks. The new crossovers and hybrids have unibody construction, I think.
