I have a '78 Chevy K10 that I keep more for fun than practicality. Rust everywhere, but it runs. I use it for hunting trips because I do not care if it gets scratched or muddy. Half the fun is coaxing it back home when something breaks.
1988 M5 BMW. Owned it for 25 years now. In the process of getting it back on the road. Maybe 100 miles in the past 14 years. Runs and drives , just finished the paint. AC next along with some other items. I do all the work etc except the paint
