Chances are u won't even get inn for your trade sorry to say I just traded my se in last week kbb said I should get 13k for trade only got 10k on a 2012 focus SE with 5000 miles on it and looked like the day I bought it. I traded for a 2013 titanium with handling package and nav. Ford is giving very impressive rebates on 2013 non-st focuses I got right at $4000 between X-plan and Ford rebates my sticker was 26k -4k =22k that is just to close to the 20k u want most people are going to just buy a new one for 2k more. Plus the dealer has to be able to make money off ur trade 20k leaves no room for profit. U are very lucky if u get kbb for ur car. Try looking up the black book value which is what the dealers use and will very rarely pay more than the black book value.
