Well, after doing a little research and calling the dealer back, the cash price would be around $19,000.00
My 1320 is six years old, great shape, and I got a good deal on it when I bought it. Believe it or not I asked a NH dealer what my 1320 would be worth trading up to a TC30 , and he said $4000.00, around an $8500.00 trade. That was tractor for tractor and I was going to keep my 7308 loader and other attachments. I figure my tractor is worth $10 -$11,000.00 with the loader if I were to sell it outright so we are getting pretty close to a cash price at $8500.00 and the 0% interest really clinched the deal.
I am moving up 6 years, 13HP, R4's, detachable bucket and a pretty cool looking tractor to boot! I am keeping my 5' finish mower that came with the 1320 when I bought it and that is a pretty good piece of change, will wind up trading for a 6' I am sure. All in all I feel pretty good about the trade, Think I would have come out about the same money if I would have sold mine and bought the other for cash.
