Which Should You Buy: Cessna 340 or Cessna 310?

Bottom line: Choose the 310 for the lowest-cost Cessna twin and unpressurised six-seat operations. Step up to the 340 for pressurisation and the cabin-class cabin; to the 414 for the larger fuselage and the cabin-class executive mission; to the 421 for the top piston-twin Cessna built (highest cruise, most refined cabin) — each step adds materially higher acquisition and operating cost.

Pick the 340 if…

  • More seats — 6 vs 5.
  • Faster cruise — 195 kts vs 190 kts.
  • Longer range — 1180 nm vs 800 nm.
  • Newer design — production from 1972 vs 1956.
  • More inventory — 82 listings vs 48.

Pick the 310 if…

  • Budget matters — from $19,000 vs $168,823, you save ~$149,823.
  • Lower operating cost — ~$280/hr vs $320/hr.
