I've been looking to step up from my Warrior and recently found a '58 Comanche for sale that's peaked my interest enough to prompt a hop this week to check it out in-person. The airframe (3,000 hrs.) looks solid and all ADs are complied with, but - and this is a big but - the plane hasn't been flown in six years. The engine was overhauled eight years ago and has just 17 hours on it. The mechanic who performed the annual did a borescope on the cylinders and found minimal corrosion; the engine also purrs.

Cognizant of the perils of disuse (especially for a plane based here in Florida), I'm skeptical a borescope is enough to determine the health of this engine and would consider pulling a cylinder to inspect the cam during a potential pre-buy. Would that, in fact, be a good idea? Moreover, given the plane's history, is a purchase even worth pursuing? The asking price is below average, but I'm not in the market for a dud! Any insight would be helpful.
