i ended up taking $53k (without snows) on a trade with dealer. i had first negotiated the cash price on new car, so i was comparing apples to apples. Anyhow, tax savings on new car equal $2,500, plus i should get around $1,000 for the snow tires/wheels.
Net-Net, it cost me about $10k a year in depreciation to drive this UDM!
plus $3k a year in insurance.
plus $3k a year in premium unleaded at 16 MPG average!
