I owned an Abarth from new for eight years, sold it this year. It was convertible and absolutely brilliant.
Before that I had a smart roadster for a few years, bought on a whim from a friend who was selling. I used it to go to London once a week. It was very entertaining and endearing but the gearbox was sooo slow. Excellent fun though and great handling. The leaking problem was worse than the mog though as the carpets were backed with two inch thick foam and sealed. Impossible to dry it out properly..
