Which Should You Buy: Cessna 340 or Diamond DA62?

Bottom line: Choose the DA62 for modern composite construction, Jet-A diesel economics and the seven-seat cabin — modern light twin. Choose the 340 for pressurisation, higher cruise and the cabin-class executive feel — accepting much higher operating cost and Avgas dependence. ================================================================ # CESSNA UTILITY (1) ================================================================
