When I was at the track at VIR last weekend I saw a Lotus-7 that had this "part" sitting on its bonnet. Having recently read the 70 or so questions to the eBay seller, I had to laugh out loud when I saw the bottle. I'm particularly fond of the question/comment where a reader pointed out that "Lucas" and "working" is an oxymoron. The seller replied that was known as the Nuffield Paradox and couldn't be helped, causing so much distress at BL that they changed their corporate logo to a clenched sphincter. The seller is highly creative and witty.
