I wonder if the OP has considered a diesel powered plane?

This example has the more modern (and reliable!) 2.0 diesel and sits in a very proven and sturdy airframe. Plenty of bag space too! For €90,000 I would expect it to be in very good condition with some half decent kit.
I flew the older 1.7 diesel PA28, loved the FADEC control and I guess the club loved the economy!
I can only guess that fuel costs and AVGas availability will become more of an issue in the future!
