One thing you can get in new planes is decent access, with a door each side.
The one-door designs which have tended to dominate the non-Cessna scene are awful.
The worst thing is a 6-seater with just one door.
Back in 2002, before I got the TB20, I looked at getting an old plane and throwing a lot of money at it. The thing I soon discovered is that such a project, done here in the UK, would be fraught with problems because there is so little expertise about. The options I was presented with would have involved parting with 5 digits but if you asked too many questions you would be asked to go elsewhere. This is not the USA... Today I would be able to manage a big refurb project, but not as a fresh post-PPL case. And I am sure that is true for most GA pilots. They are smart enough to know their limits and won't even try it. Until you have been in the ownership game for a few years, you don't have enough good contacts, and most other owners are of limited help because most buy a plane, run it down, and flog it...
