I wanted to somehow get the attention of the red S line owner, get them to stop and inform them that they should have got chrome exhausts with their car... I wanted to tell them that they'd been bilked... I wanted to get their assurance that they'd be straight down to their dealer for what was rightfully their 'extra'... alas, there was a red light and many cars between us by the time he / she had passed on by. They'll live on in ignorance, probably, while dicks like me will notice the smallest thing... and somehow judge.
