Another recommendation for selling yourself vice selling to CARMAX, etc....
I have sold and purchased multiple cars on craigslist; autotrader and autotrader classic. Craigslist is much more common for car enthusiast (classic; specialty cars, etc.) because you can find some great bargains. Autotrader is fee based, so it does have a little more of a barrier to limit bogus car sales. Although, most illegal car sales on Craigslist are easily identified based on sales price and comments that "flag" it for most buyers.
Regardless if you do sell yourself recommend you consider the following:
-Pictures: exterior; front/back; both sides; maybe engine bay & interior; craigslist permits multiple pic's; believe up to 12 at this point.
-Maintenance/receipts: Car has really low mileage, so not surprising if you don't have a lot but any documentation is helpful to show the car was maintained. Original purchase documentation is also good to show how much the car sold for and whether it included any special order items.
-State DMV: As others have mentioned reference your states DMV for private car sale documentation. They usually have a good bill of sale example and a link to notify the DMV when the car is sold.
-Contact info: Craigslist also lets you list an item with only an email account for contact, so this does provide you an easy way to "screen" out people before agreeing to meet. You decide who to follow up with and discuss the car. You do need to be careful about who you meet and if you price it low, expect a lot of emails because "car flippers (buy & sell)" are very aggressive in closing deals quickly. If you do provide your number be sure to mention if you want "text" or not.
-Payment: Lastly, I would recommend NOT using your bank for the final sales meeting because in my experience unless it is cash, your bank will not be able to verify the cashiers check; a couple days hold is likely. So unless you do a cash transaction, I would meet at the "buyers" bank so you know the cashiers check is legitimate or conduct a wire transfer of funds. It depends how comfortable you are with the purchaser and obviously where they bank might also be an issue. Cash obviously works, but make sure you have a "fraud marker pen" to check the large bills and a plan to get it deposited ASAP.
Regardless, how you decide to sell, I expect it will be a quick and easy transaction based on the mileage and car model. Good luck & have some fun with the process.
