Anytime a trade is involved, it's harder to determine how good a deal it is. For all we know, you could be trading in something with blue book value of $8k, so $4750 would not be good. Or, flip side could be book value $3k...
In my book, any deal you walk away from feeling good about is a good deal. For what it's worth, I bought my '10 JP via email, and after I got the price negotiated to what I wanted, I then worked in 25% off accessories at the time of purchase. The dealer initially did not want to go over 10% off, then 15% off, but I held my ground & after a few back & forth emails, the dealer agreed. I ended up spending $2500 retail on accessories and got 25% off.
All in all I was happy with the deal. I know now, after the fact, that at least 1 member of this forum got a better deal than I did. But, he did purchase later than I did, so the motivation to get the '10's off the floor was probably greater than when I bought.
Hope you can get the deal you want...good luck!
