I feel ya. Are you in Britain? I went through a slew of supercars- 6 Ferraris, a Diabo 6.0, a Porsche GT2 set up as a club sport as well as a bunch of others, including a 993 c4 cabriolet and a pre-war car. I bought a Super 3 recently to get away from bikes --I'm getting old, I don't need speed as such. But you want a stick, I assume, a visceral drive, and something that isn't a headache to deal with. I had two of the newer Mini Coopers- one was set up as a "works" car and it was a "twitchy" daily driver. I'd look at serviceability and parts. FIAT was never really successful in the States- a stepchild at best (though I had a 124 sport back in the day and always loved the feel and look of the Italian cars). I'll follow this thread with interest. If you are in Britain or UK/EU, you have different choices than us Yanks.
Not a bad place to be, where you are asking this question. I get it.
