Bought via a classified ad on Ebay, underneath the seller's name was the 'Motors' icon, which when you roll over it confirms that the seller is a motor dealer.

The classified ad invited 'best offers' and my offer was accepted. No mention in the ad of 'sold as seen', 'without warranty' etc and price was £23k.

The seller contacted me once my offer was accepted, and I asked what warranty he would give on the car. He told me he was not a dealer, but a broker for a private seller, and that the car was being sold without warranty. I told him no deal as he was passing himself off as a dealer with all that that implies, he said he would sue me as I had made a legally binding offer. Who is right?
