Buying a new car? You have two main options to get rid of your old one.  The first is to trade it into the dealer that is selling you're your old car.  The second is to sell it yourself.  Which is best?  For many people it's just easier to let the dealer take it in trade but for others, selling it via private sale is preferred.  Considering the later?  Here's a guide to get you going.

Pick the best sales avenue - For most sellers it's either sell your car on Craigslist or on eBay.  eBay is an international marketplace with millions of potential customers.  If your car is in good shape, has low mileage or is an unusual model, eBay might be the place for you. The other avenue is Craigslist.  Craigslist is by definition a local marketplace so you will likely sell your car to someone nearby. 

Take lots of pics - We can tell you with certainty that if you take just a few pictures, you won't sell your car for good money. Use your cell phone and take 20-30 pictures. Take pics of all four sides, the interior, the engine, the odometer, even underneath if you can.  

Write a smashing description - Write a thoroughly detailed essay about your cars condition, what you've done to it over the years, how long you've had it, whats good about it and what it needs.  Be honest, not only will you buy trust from your buyer, you will avoid any buyers remorse after the receive the car.

Price it right - If you are selling your car via eBay's auction service, put on a low reserve.  eBay's own research shows that low reserves produce higher sale prices, because once the reserve is met, the bidding takes off. On a Craigslist, research what other people are asking for similar cars and price your accordingly. Don't try to ask for what is over the market value of your car.  The market won't pay it.

Post it at the right time - If you're selling on Craigslist, post the ad on Thursday so it's not lost in the billion ads when the weekend arrives. If you're selling through eBay, end the auction on Sunday evening. Post your phone number and be available to answer your phone while the ad is live. 

Good luck!
