Better the Devil you know maybe?? Once you've replaced all the sprocket wobblers, and left threaded valve compression differentials.. Then you've pretty much got yourself a new car. Having said that, there's also throwing good money after bad... In my book once the body work is starting to cost big time, then its fond farewells. A couple of years back. I was really lucky. My ancient estate car was going to cost £500 to get thru Mot.. Neither too much, nor too little, to be able to make a decisive call on repairs. Then, someone spotted me a bargain hatchback for £250 - 10 months mot, And then unbelievably I sold the engine out of the old one for £180. With cheaper tax and insurance for a smaller car, which was all I needed, I felt like a proper winner for once.. Just occasionally, things land sunny-side up..
