This is the third time i've written this, but the first time i've manage not to reply to myself. Mmmm - definitely need to improve my forum-using skills (much harder than getting the hang of the e-class estate). Anyway, to all those who responded - thanks so much for the invaluable advice. I'm off to buy a lotto ticket as i've found a w124 300e diesel estate (neither blue, nor silver). Would any of you wise people be bothered by a 17,000 gap in the service history (from 127,000 to 143,000). It has done 144,000 miles and is ten years old. Am going to look at it asap, but don't want to get carried away by its apparent rarity value (specially since i am a merc virgin and really don't know what to look for.)
