Hi Lucy!
We have a Peugeot 306 cabrio ("nice carrrrrrr!" :D :D :D). Monty fits on the back seat in his seatbelt harness, wind blowing through his ears. It's great fun to drive! <evil grin>
Downside: you get deafened by the radio/cd being so loud, so as to drown out the road noise above 65mph, even with the roof up - NOT good on the motorway! You worry about where you park in case someone decides to slit the roof. Baseball caps essential for the topless experience :p - keep two in the glove box at all times!
Everyone tries to burn you off at the lights. :rolleyes: Perky gearbox encourages you to drive a bit too assertively.

It's a while ago now, but we test-drove a saab before we chose the 306 and decided against it because, although it was faa-aassst, it was a bit twitchy and light on the steering. Fun for a while but we didn't think we could live with it.
So we went for the 306, which is a good, positive driving experience. Even after 6 years, it still makes us smile! But it is too impractical for everyday use, so spends far too much time in the garage on its own. :( I wouldn't have a cabrio as my only car, especially if I did a lot of driving.
