I have been looking to purchase an airplane for some time now. I want something high performance. But the future of avgas is making me hesitate. Warbirds and high performance aircraft will seemingly be the type left behind as unleaded variants come out. While it may be some time until this happens, it is already difficult enough for sellers, especially if their model may become obsolete (or require re-engining) in the near future. I don't want to be in that position in 5 years.
Will turboprops or diesel powered variants gain wider acceptance? Thanks for your opinions.....
