Blue Book value for my old car in “fair” condition, is $3,250. I’ll be happy if I can get $3,000 for it.
No dealer is going to give you anything even close to BB value on your trade in. You’ll be lucky to get WHOLESALE value. They have to make money somewhere and they aren’t going to buy it for what they MIGHT be able to sell it for (unless the “new” car price is inflated enough to cover the old one). You’ll be better off trying to sell privately if you need to maximize the amount you’re going to get on the old car…
