Probably my European trip (Germany/Czech Rep/Poland). I rented an M-package BMW 3-series and maxed it out several times on the Autobahn. Got a speeding ticket in Poland, did 180 in a 130, the fine as charged by Hertz was like 30 bucks and change, lol. Totes worth it. Poland was beautiful and super cheap. Polish chicks are gorgeous. 😍
