Beechcraft Twin Bonanza Aircraft under $500,000

Under $500k for a piston twin is the mid-range — typically 1980s-90s Baron 55/58, Cessna 310/340/414, Seneca II/III. Engines on first or second overhaul; mandate-compliance largely current; pressurised variants need pressurisation maintenance verified. Reasonable middle of the cabin-class twin market.

The Beechcraft Twin Bonanza (Model 50) is a large 1950s piston twin produced 1951-1963 — much bigger and heavier than its Bonanza single namesake. Originally built for business and military (L-23/U-8 Seminole) use, it is a robust, characterful classic twin with Lycoming GO-435 or GO-480 geared engines and a four-to-six-seat cabin. Slow to find on the used market; for collectors and classic-twin enthusiasts.

Typically six, in a notably wide and roomy cabin for a piston twin of its period.
What were the military versions of the Twin Bonanza?
The military operated the Twin Bonanza as the L-23 and later U-8 Seminole, in liaison, transport and utility roles.
Is the Beechcraft Twin Bonanza still flying?
