Ah, ya weenie! Have some fun!
I got stuck with a 1.4l (16-v) VW Golf in '99 for my first Autobahnen experiences. But I topped it out anyway. Redlined in 5th gear, slightly downhill, at 190 km/h. The little sucker would have done more, but I figured it's bad form (as well as damned expensive) to puff the engine in the rent-a-car.
Three years prior, I got one of the then-greatest small sedans ever when I rented in Rome. An Alfa 155 1.6l 16-v. That one did an honest 210 km/h on the Autostrada - which I later discovered had a speed limit of 130. I also got the 4-hour autocross of a lifetime (Less than 5 minutes, total, above third gear!) when I drove the Amalfi Drive in it. =8^D--
