Beware! You might find yourself grinning, or even laughing out loud. Addiction will then start to creep in...
I took a friend out for a drive yesterday and he was afflicted just so, despite being slightly car sick at the end of the twisties. He races (has raced?) Porsches and flies a single engine plane, so that surprised both of us. He was still grinning like a mad man, though.
On a side note - the engine really likes cold air. It was very "peppy" in the seven degree weather.
