several Minis, I'd always choose one over a Bini. Driving one always gave me a smile on my face. Working on one not so much (spare marigolds anyone for the dizzy)
Not as big as driving my Pug 205 1.9 GTI. Easier to work on, and more like a go-kart in the linear throttle response.
The Smart Roadster we own is also good fun - 700cc rear engine rear wheel drive - coupled with good all-weather tyres, makes it also fun to drive. Similar to work on to the mini - removal of the back panel usually needed.
