I think you should test drive a few cars, then get a 6-speed manual 2014-2016 Mazda 6. It will be the cheapest of the options you're currently considering. Then take all the money you're saving, bring a couple buddies and do one of those track-day-in-a-supercar things every year. Avoid that red ball of rage that is a European car breaking down and then getting jerked around by the dealer.
I would submit that the Mazda + supercar strategy will increase your overall happiness more than just getting a nicer-but-more expensive european car that you know you're just going to get used to like you did the Accord. The hedonic treadmill is real.
