Anyone can FLAG an item though- so, it could be another craigslist user, a competitor, or the site "moderators"- Get creative with your Ads and post on more than one section... at least it is FREE and on more than one section, it may get seen a couple times before getting flagged...
I would also stress right up front that you are a Local Dealer- (even w/in 100 miles of your actual residence)
and if you are putting out a mass ad so it hits over state borders and such... well, good luck But you may want to look into a bit of an advertising budget... Get an ad in a local "Community" mag- a "gig" publication, etc etc

TARGET your Market - Business will come...
