I totally agree with Doug, Will & Alphonse on this one. That dealer is crazy thinking he can get you to trade a newer Kirby G4 for a Heritage II AND get you to pay extra cash! At the most, he should be doing a straight-up trade.
Here's what I would do....for starters, if all you want the Heritage II for is so you can have a Kirby with attachments, then just buy a set of attachments for your G4. But if you really just have your heart set on a Heritage II & prefer it over the G4....go back to the dealer & tell him in no uncertain terms you think he's being unfair asking you to pay extra when he's getting a newer Kirby that's 10 years newer. Tell him that you will ONLY do a straight-up trade, or no deal. If he calls you on your bluff & doesn't give you the deal, then walk out & sell your G4 on Craigslist, Kijiji or Ebay. Then go buy yourself a Heritage II, & then go back to the dealer & tell him you got a Kirby elsewhere & maybe next time he ought to re-think how he negotiates with customers, & that's why he lost a sale.
