I completely understand. I still have my 71, btu except for maintenance, it doesn't need anything, any more. In fact, it's now down in Florida sitting in my garage at the condo. This spring it will probably make it to a few local car shows, and act as a back up car while we are down there, I have no plans of dong any major work to it, ever again.
Might do a truck, but if I do, it will be one that has all of the body, chassis, and suspension work already done, and just needs an engine/trans installed.
My daily driver is a new truck, and you'd be surprised how little attention they need. Essentially, 4 oil changes a year and 4 tire rotations, and air filter service. Shocks, and a timing belt at 100K miles, and you're essentially good to go. Bumper to bumper warranty to 100K miles, and now available to 250K miles.
