Summer is officially here. And so is the 1st heat wave of the summer. But one good thing about unbearably hot days is that you get some pretty nice nights. Which is a perfect time to drop the top and ride off into the sunset. You have a choice of German 2-seaters for your ride; the now classic BMW Z8 or the possible classic-to-be Mercedes AMG GTC. While I am a Mercedes man first and foremost, I can’t resist the allure of that NA V-8, and more importantly that shift it yourself transmission. Which one will you take?
