eBay is not necessarily a bad thing, I have had nothing but positive experiences in my transactions via eBay. For eBay I just watch for the buyer's feedback history. But there are a lot of horror stories of the scams and shenanigans that happens to others too. Craig's List has worked out well for me too. On CL, it takes patience and not just sell on the first person with an inquiry.
If just signing up for eBay, you might not be able to sell. I don't know if they lifted that restriction of having 10 positive feedbacks before you're allowed to list (sell).
Forums would be the best bet, as the buyer is most like a 4Runner enthuiast too.
