Don't know what you mean. I'm LEZ exempt last time I checked, probably because the joy (see also : impotent outrage) they bring to the beholder offsets any "dirtiness", real (mud) or perceived (it's actually a fairly efficient 2.5l diesel, nothing for anyone to get "all choked up" about).I'd love one of them, but living inside the M25 I can't afford the hundred quid a day or the work to make it compliant.
