Well if I was really rich it would have to be an L-39 (or the L-159
) or a Spitfire (Any Mk as long as it was an authentic Spitfire and if it flew for Canada even better) or a Mustang (I have been in a dog fight against one
) or a BF109 (three remaining I think)
If I was reasonably rich but not LOADED!!! I would be more then happy with a Harvard flew in them before and they have a great Canadian story behind them too.
If I was going to be impractical I would try and find an old Lancaster or Halifax (If they were ones my grandfather flew in the better (They have probably been demolished long time ago)) and rebuilt it if necessary (of course with a team of AMEs).
And if I were to be really unpractical my fleet of warbirds would be as following: Lancaster, Spitfire, BF109, Mustang, T-28, Harvard, L-159, Tutor (Snowbird paint if allowed) and to round things out a Saber (painted like to Golden Centennials)
