Craigslist is still the best way to sell a vehicle, IMO. You can generally ignore the scammers, who will usually contact you within 24-48 hours of you posting your vehicle. There is no point in reporting them because just about every single item that is listed on craigslist is fished by scammers. My favorites are the ones where they ask if your "item" is still for sale and how interested they are in your "item." You are also sure to get some car flippers who lowball you without seeing the vehicle.
When I sold my vehicle I listed the address where it could be seen and only responded to anyone who actually looked at the vehicle and were interested. I also include a line stating that if the ad is still up on craigslist, then the vehicle is still for sale. Doing these two things cuts down on a lot of nonsense.
When you agree to sell the vehicle, agree to either all cash, or a cashier's check and meet the purchaser at their bank, where you can watch them get the check and where there will be cameras.
