Buying advice sporty car (used car) 6 cylinders, V8 experience Audi S5 RS5, BMW M3, Porsch

Servus Now I am about to buy a car and wanted to get some opinions, clearly the decision still makes me in the end. What I am looking for: -“something sporty” this is the main criterion -sports car/coupe would be my favorite, but doesn’t have to be -6 or 8 cylinders -300hp+ better still 400hp+ -budget about 30-40t€ -German manufacturer Actually I wanted to get an Audi S5. Here in the forum there are a lot of posts that keep me away from it (Mot Then I looked around for an Audi RS5: class car! Soon I’ll have a look at the M3 E92. Visually, however, the vehicles are a little too discreet, because a bit the visual emotion is missing. Also a Porsche 911 (993 all dream!, 996 4S/Turbo, 997 S) or Cayman S (Coxster) would appeal to me. So if someone had already had experience with one of the vehicles, I would be very grateful to have their advice! 😉 Maybe someone knows more/other alternatives? I think I mentioned everything important. Thanks for the first and best regards from Bavaria! Peter
