Buying a Bonanza A36TC Sight Unseen and Flying It 2200 Miles Home!

We bought another Beechcraft Bonanza! We just purchased this 1979 A36TC sight unseen out of Florida, and proceed to fly it home 2200 miles in just 24 hours! We have bought two other Bonanza F33A’s so this makes our third Bonanza. This flight lasted 17 hours, a far cry from the few hour flight in our recently acquired Cessna Citation 501SP last video. What mods or upgrades should we do to this plane? Avionics? New paint, interior, engine?
