Austin-Healey 3000.
Nothing else comes close ..... except for the BMW 507 of course ....
Oh waidaminute ........
If you're talking actually having owned or driven, that would be my current BMW M Roadster (2006), but the Mk II Austin-Healey Sprite was a close second as driving experience at the time. How I survived the Sprite after closing time back in Jolly Old I'll never really understand ..... [not me of course, the other road users staggering out of the pubs]
