Yes – quite agree. Although as customers we have not got to the point (I hope) where we brand ourselves with the logo, like the odd 'Hardly Ableson' owner does, there is still a huge potential available to MMC for relatively little outlay. A revised web site with added bells & whistles could do them a power of good. Funnily enough, BHM are currently in the process of re-designing theirs – perhaps you should give them a quick call....?
As to costings, I suppose it depends on if they are looking to change everything at once, or use up old stock of stationery, merchandising etc. first, but I suspect they'd have to fork out set-up costs for new stamps / dies / moulds etc on everything from dealer publicity material right down to the bit on the key fobs.
