I have used CL to sell trailers (2) and numerous other vehicles. After I clean my vehicle so it shines, I take numerous pictures. Then I do my homework and check out CL to see what my competition is and how they are priced. I try to price mine below the average asking price and make sure it is above average in condition. Then when I write my ad I describe everything about the vehicle that an interested party would want to know, warts and all and without abbreviations. This includes mileage (on a car) and price. I don't know why anyone would write an ad and not list these 2 items unless they were ashamed of it or trying to hide something. By writing a complete description, you may eliminate some looky loos but they are not your target market anyway. I have used this system for many years and I have always sold my vehicle to the first person who came and looked at it. Things like NADA can help you in pricing but the real price is market value and that is driven by your competition.
