Can't remember if this has been suggested, but what about a searchable
directory on the forum of Web sites, Companies, people ect who have been used by and recommended due to price, quality ect. The services and what they do, the vehicles they are relevent to, links to their web site, address's and all other sorts of info.
Not so much the big companies, as say listed on milweb, but more of the obscure ones such as knobs, buttons, types of fixings, brackets, wiring, brake piping, hose fittings/pipe ect, I am sure you all know what sort of thing I am on about.....
