Agree with the "something tame" approach to start off with. I have one of the rare aerobatic Beech Sundowners. It's a decent tourer; 4 seats, good useful load, nearly 6 hours endurance, 180 hp so it climbs OK. Not overly fast: 105 knots and you're having a good day.
It's cleared for barrel, aileron and snap rolls, loops, Immelmans, Split S, spins. Lots of fun for the average punter. Six g's positive, 3 negative, no inverted oil/fuel, weight/CG limitation for aerobatics.
I would be surprised if there are any in Europe but there were aerobatic Musketeers and B19 Sports, and you might find one or two of those around. They are built like the proverbial brick sh!thouse, but the old 165 hp Continental engine might be problematic (parts availability); the Lycoming engine examples are a better bet.
