I'm the same. I get attached. Haven't sold a car since parting ways with my crx in the late 90s. An ex pressured me into it and the del sol I bought after it was nowhere near as good. And I die a little every time i see an old bronco at a car show. Bought my 71 back in high school when they were still cheap, sold it a few years later. No way i could afford one again. Now i keep them forever or until someone hits me. My D16 was in fine shape last i started it but that was over a year ago. Im afraid of how it might smoke now. Thought about a turbo too but I think now that car might just syay NA, get some suspension and brake upgrades and a new timing belt and turn into a rally crosser. My issue is always more about time than money. That all being said, I keep old cars but also have a reliable daily driver. If it came down to spending 6k on an engine rebuild to keep driving to school and work I'd bite the bullet and find something reliable for cheap. There are decent, albeit less fun cars in the 5k range and a car loan is way more affordable and attainable than an unsecured personal loan.
