If it's the Forester and the buyer didn't pay, you should have opened an unpaid dispute against them. You still can as it was only sold 2 weeks ago. Open the case, they have 4 days to pay, if they don't, you close the case after 4 days and eBay refunds your fees. The buyer also gets a strike against their account. If they get 2 strikes, they will find they can't buy off a lot of people who have blocks in place.
That's one of the pitfalls with selling cars on eBay. A friend buys cars, does them up and was selling them on eBay. He had more tyre kickers than successful sales, so he gave up. I also know a few other people who would get lots of bidders, then the winner refused to pay.
The other option is, if the winner refuses to pay, once the unpaid case is closed, you can send a second chance offer to the second highest bidder. They may not accept due to the time lapsed, but you never know.
