Interesting discussion. At the higher end of the price range (ie. DA42, SR22) I would be very tempted by a used Malibu.
I've only flown a few hours in these. A bit cramped for the very tall pilot.
The Lyc engines have been troublesome, but most should have had all the ADs done.
...but for travel across Europe, none of the normally pressurised singles compare IMO. Quiet, pressurised, air-conditioned comfort. Cabin class seating, airstair door. Known-icing. The range is over 1000nm IIRC.
