Considering an A4. How enjoyable is the top-down ride in the cabriolet? Hard to tell from a single test drive. I've had many convertibles and some are a blast to drive top-down, and some have annoying turbulence and buffeting that can really ruin the experience. My 1992 Camaro I could drive at 70 mph on the freeway and it my ballcap wouldn't blow off ... just a pleasant breeze in the cockpit. On the otherhand, I had a CLK 320 for a short time that had a wierd vortex that would often gush in from the rear seating area that was extremely annoying. What do you think of your cabriolets? Thanks!
