| Main trade-off | Good speed and range for a classic twin, but tip tanks, turbo engines, gear and age make maintenance demanding. | Excellent twin-engine efficiency and range, but ageing structure, fuel system and two-engine condition create substantial valuation risk. | The PA-23-250 Aztec D combines 6-seat piston-aircraft utility with about 449 NM reported range and about 183 kt reported cruise, while payload, runway and operating-cost figures remain indicative and should be verified for the specific aircraft before making a decision. |
