After close to 3 years owning my first car (MX5 MK2, no ABS, no TC) I just had, for the first time, the rear step out on me today.
Dual carriage means I had to do a 180 at a roundabout to drop off my girlfriend at the train station. Happened regardless of the roundabout actually as it was when I gently accelerated after straitening up. Actually happened twice as after I originally noticed what was happening I immediately stopped accelerating before trying again and the same thing happened. Third time was the charm though and pulled away fine.
Nothing obvious on the road but at around 8:30 could have easily been ice up here in Scotland.
First time I've ever felt the back end twitch on a real road.
