'New' trailer full of rust

I recently obtained finance to purchase a leisure trailer. After receiving the trailer I noticed that the new trailer is not in a new condition. There is rust spots, damage to the nose cone lid and paint chips on top of the trailer. <br> <br> The dealer from whom I purchased the trailer (Diesel Electric / Outdoor 4x4 Welkom) has offered to send the trailer in for warranty repairs. I would not like to send a 'new trailer' in for repairs. I feel that I should have been issued with a trailer that is in perfect condition. <br> <br> Please be so kind as to contact me with advice as to what I should do next otherwise I will contact my bank to cancel the deal and return the damaged goods.
