What about a sticker that would go on the number plate- over the dealer slogan? I don't remember them giving me anything to advertise for them!
Or advertising on ebay? My boyfriend was looking for something for his Honda CB1300 and when he put the key words in he got a listing that advertised the owners club (amongst the other listings), just a thought.
I told my dealer about the site the other day - he may pass it on you never know. i also told my uncle who picked up his new Civic last week - i'm trying!!!!
