stinking craigslist

i have a friend that's now advertising a $31,000 dollar car on Craigslist, in the Parts for sale section, instead of the cars and trucks for sale section, as he doesn't want to pay Craigslist 5 bucks to list the ad.
C'mon now, it's like complaining others are doing about paying Pay Pal the 3% fee for doing business by Goods & Services, or people getting scammed by sending Friends of Family.
5 bucks is dirt cheap to list a vehicle for sale.
