Like the Bonanza single, the Beech Baron gets high marks from pilots for its solid and predictable handling, good construction and comfortable cabin. Plus, with its rear cabin door, the Baron 58 series is passenger friendly and easier to load stuff inside compared to the smaller Baron 55 twin.
The other thing the Baron has going for it is supportability. The airplane is still in production today (as the Baron G58) and it won’t be tough to find a shop that can wrench one. But maintenance won’t be cheap and you don’t want to skimp on transition and recurrent training. You’ll also want to get an insurance quote before making a deal on one.
