Too many to mention. I haven't been in anything exotic but for me that's not the point.
Hell. I've had some laughs with my uncle in his rep mobile which is an '07 Ford Mondeo TDCI estate. He doesn't half give that thing some stick. I'm suprised it's still in one piece. Considering he's 42-ish now, he's a bit immature but it's funny anyway. Axle tramps, wheel spins, handbrake turns, driving over speed bumps at such a speed that it bottoms out, it's done it all.
He use to have a BMW 320i E30 quite a few years back. He was forever trying to get the back end out in that thing. He even tried it in snow and almost binned it on a corner.
The best experience(s) have to be going to the WRC once a year in a Subaru Impreza. Goes like hell, sounds like hell, corners like hell. Last time I went in it, it was being driven that hard around corners it felt like my face was being pulled off. Roundabouts + Impreza + Speed = Lol.
The scariest driver has to be my dad though. A wolf in sheeps clothing is an understatement. For someone who's 47 he does some stupid things. We came up behind a lorry once in the Fabia, came up to a blind left hand corner, my dad put his foot down and over took it. I thought it was foolish but he found it funny. Races anyone who he thinks has the look on their face of "Bah! It's a Skoda, we'll have that!". It does make me laugh.
