This tub new retails around 12,500-14 depending on the options. If I had this tub as a used tub to sell it would be 4-5k depending on the shape and what I paid for this tub. If this was a 2 pump system (Signature) 3-4k as Tman122 mentioned, but this is a Legend. Also if I was going to offer a warranty that may make the price different. Can you negotiate yes. This tub has 61 jets with 3 4hp pumps. What was the price you were offered?
