As others have mentioned, do not send a deposit for a car you have not seen in person.
10% deposit is rather large. You guys should settle on a smaller deposit and get it in writing where both of you sign the document saying you paid him a deposit and you can get it back later if the deal doesnt go through. I sold used cars in the past and the deposit is usually a couple hundred dollars as a gesture to hold the car until you can get financing.
