I agreed the sale of my car (a 2011 Volkswagen Golf GTI) to a guy who buys cars on behalf of a trader. He left a £150 deposit (just over 1% of the value) and told me he'd be back with full payment. He called the next day to come over but I was out and he said he'd call back.

This was four days ago and when I call him someone else is answering his phone claiming they don't know what I'm talking about. The dealer he said he worked for isn't answering their phone either. I still have all the documents and the car. All he did was leave a deposit. What are my rights? Can I sell the car to someone else?
