on my way home yesterday after dropping something off at a friends place, saw an old crappy 1999 clio following me enthusiastically.
eventually i pulled into the lane to turn left to my place and he pulled alongside me going straight.
he was hanging out of the window looking at my car and when i looked over he looked like he wanted to say something so i turned my music down.
He said "Fast car huh?"
So I said "yeah nearly 300 bhp"
He's like "How Much!?"
So I say one more time nearly 300 and he just replied with "Jesus" and drove off. (his light had already been green since the start of the convo lol)
As he drove off he was still hanging out of his car looking back at mine.

Very satisfying
