Do: Take tons of pictures for your listing
Give any prospective buyer a walking tour of your car and take at least 24 good photos. Start with a picture of the ¾ front (with the car facing the camera at a 45 or so degree angle -- more or less depending on what looks best) and walk around the car, opening the doors and taking the pictures as if you're giving the "buyer" a tour for the first time. It'll make buyers feel more confident in coming to check out your car in person.
Don’t: Ignore the car's flaws
Make sure to take plenty of pictures of the interior even if there are cosmetic issues. It sounds contradictory, but I have sold vehicles for far better prices by showing and even highlighting defects because it establishes an air of honesty.
Do: Be realistic about your asking price
You can’t expect a premium price if what you’re asking for is just sky high. I find that Edmunds has the best ‘Private Party’ prices while Kelley Blue Book thinks you can buy a perfectly nice minivan for the same price as a Chinese scooter. As for those cars that are $10,000 or more, Autotrader and Cars.com tend to offer a decent market price.
Do: Write a good, clear ad
When it comes to the internet, a well-written, professional-looking ad attracts far more money than one that looks like it was composed by a manic texter. Remember, you’re writing for money.
Your ad should focus on four key attributes: maintenance history, noteworthy features, the reason why you first bought it, and what you have done to keep it a nice daily driver.
