20-30t €, desire for fun with performance and absolutely helpless? Convertible or Closed?

Hello you car fanatics! As one of those who are often on the road here myself I am absolutely at a loss at the moment. The desired car should: make fun! Cross- and longitudinally dynamic be solid, 1-2 a year in the workshop must be enough. Payable insurance (so max. 2t € per year) max. 12-13litres on 100km) 200-400hp, that’s all it has to be. All year round Suitable for use Current situation: Currently I own an E55 AMG W210 in good condition and a Lotus Elise S2 Rover 122hp. Both vehicles which are really good in their segment, only the compromise is not possible. In the city the big Benz is annoying, the Elise is simply mega uncomfortable and thanks to the GFK body also reluctantly just parked somewhere. In addition, there is the E36 320i as a winter car, which is no longer worth processing and probably still drives for 2-5 years until the TÜV or lack of pleasure at the car divides us. The motorcycle, a Suzuki SV650SA stands more than that you drive thanks to the Elise unise un d I would also like to move more often. Everything together just does work and I need and don’t want 4 vehicles anymore. Conclusion: I want to be a day-to-day full-year fun car again! ALSO WHAT TO BUY TO ME? I am between BMW 130i, M135i, Civic TypeR, 308 GTI and Z4 3.0si or SLK 55 AMG and Mazda MX-5 torn back and forth. Alternatively, there is the really cool/future-proof Lexus IS300h who drives really nice and hardly needs more than 6 liters. Answers!
