What to check before you buy
Engine time & compression, hours since overhaul drive both price and your next big bill.
Logs & damage history, complete logs and no damage protect resale.
Corrosion & AD compliance, especially on older airframes; get a pre-buy from a type-savvy mechanic.
Avionics & ADS-B, confirm it's equipped; upgrades are costly to add later.
Model-specific: TTx-era airframes (2013+) bring a clear premium over 2005-2010 400s; engine/turbo time and composite inspection history matter most, turbo and glass are factory-standard, so neither earns an upgrade credit.
