I've seen a little of the same in my search for the best 252 I can afford. For me, I plan on financing a large chunk of the final purchase. I guess if I found the right plane, with a 'worn' engine for $25k less than the average, I would buy it and have it immediately overhauled while financing the additional $25k into the overall figure. Yeah, it's more financing, but it would be the right plane for me with a 'new' engine at the right price. It's a little more headache, but at least you have a starting point for the engine, vs hoping for the best on one with 800 hrs to go to TBO.
