Question for the community... And yes I know get a proper prebuy, but I'm asking if it's even worth investing in that or just walk away. '62 Cherokee 160 that was long ago upgraded to 180hp. A couple years / 100 hours ago someone top overhauled the cylinders, etc. It's still a 20+ year old 2000hr engine though. Oil analysis comes back clean, supposedly, but that was the one piece of paperwork he didn't have in the plane that day. Otherwise you can see the pride of ownership involved, hangared, clean; but poor guy is losing his mobility and can't climb on the wing anymore. I know it's crystal ball stuff, but did topping that engine actually buy any time and is it worth anything or should I just plan/budget on immediate OH? Is there any way to inspect the bottom end without basically overhauling it anyways? Where I'm at I'm going to need ADSB immediately, and it's such a sparse panel (only one old nav/comm) that my "Year 1 budget" needs to be panel. I don't really dig operating in Class C with just one old comm. If this is going to be purchase + panel + engine all at once, I'll just walk away as if that engine has no life left it's not a good deal.
