Dear Mr. Thunders, We would like to introduce ourselves. Our company was organized only two years ago, but we are one of the largest boat companies in California. As you know, your son bought a boat from us recently, and I think you know how pleased h e is with our product. Also, John Webb, one of your son's friends, has bought a boat from us and, w e understand, is very happy with his boat. We are always happy to know that our customers are satisfied. We are writing to you now because, as you know, your son has decided to buy a larger boat, and we need your signature on  the loan(贷款) papers. The loan application has already been signed b y Danny. As you will see, there is one form to fill out, and there are three contracts to sign. Danny's 26-foot boat was returned to our San Pedro Dock yesterday, and we are pleased to say that the new 36-foot 'Challenger' will be delivered(送达) two weeks from today. It is being inspected by ou r manager right now. The auto-pilot(自动领航仪) has already been installed by our mechanic. It looks as though everything will be ready in time for delivery. All we need are the signed contracts from you. Thank you. Sincerely yours, Tony Valention 59. This is a letter Mr. Thunders received from _______________. A.
