One correction....ads for "Parts" or "Wanted" ads are free, but if you are selling a car, there is a small fee ($15) which will provide an ad with up to 6 pictures that will run for a minimum of 90 days. I do ask that if you are going to sell your car that you place the ad in the classifieds (and if you click on "all ads" while viewing a category, you will see many more ads in there).
If you do place an ad in the classifieds, it is then ok to place a notice here in the forums with a link to your ad. But the classifieds (for cars for sale) is one small way I help offset the cost of running the forum.
