Today might be the day...
So I plan on going from a 2013 Mazda CX-5 Sport Manual (FWD, 6-speed, 31mpg) with 36,100 miles to a 2008 Honda Fit Sport Manual (FWD, 5-speed, 33mpg) with 56,700 miles.
They suggested $15-16,000 in trade over email. There's nothing wrong with my car, so I plan to push for the top of that range. (I know it's a bit more mustachian to sell yourself, but I'll be getting a full tax break on the purchase this way, and I've dealt with selling a car myself a few times before, and I'm just not up for the stress!)
And they are asking $10k, which is a little lower than KBB/NADA and slightly higher than Edmunds.
I actually plan on talking about the trade first, after my test drive, and once I get that nailed down, try for about $300 off the asking price (about what any salesman can manage without "consulting" with management.)
