Yeah as of last week the market was $44-45k for cars with 36-45k mileage and $47-48k for sub 25k mile cars with clean carfax.
Not really a hack but I was watching the market. When I saw a big overnight price reduction and it happened to be a color they liked, I recommend they pounce on it.
Not much negotiation on the purchase price after it was already reduced below market (they came down $500 but weren’t willing to do the $2,000 price cut that was asked). MB dealership.
