The Caddy forum in the US was a wondrous site, a bloke, sorry guy called Bobinski or somesuch told us things about the development of the N* or NorthStar V8 that left me sitting there with me mouth hanging open. The crush on bearings followed by hours at 6000 rpm before doing all again a tenth of a tho' up etc., etc. The Mercedes site had a load of people talking about how many times they'd polish their cars in a week. (Bloody things would probably be broke, so polishing them was one way of passing the time.)
My neighbour pal had a Viper, so it's possible I looked things up for him.
So, if one does not really care about the site - i.e., I don't care if someone knows I get turned on by the fact you mustn't used Helix but 'TimeCert' thingies to repair head-stud threads - I'll assume it doesn't matter much, relax and go back to my book on Head Up displays.
