Having spent 7 year in the car business, the statement of only being a $3000 difference in model years isn't exactly true. While no one pays MSRP on a vehicle like this, the dealers will be clearing the lots for the new year models. The APR's and rebates from the manufacturer will be better on the outgoing vehicles.
Right now (in Texas) there are $6000 in rebates or $2500 rebate and 0% APR for 60 months on the 2014's vs $1500 rebate or $500 rebate and 3.9% APR on the 2015's.
It's a mute point since they decided on something smaller. but it's always best to wait until the new models start coming out because that's when the manufacturers have the best incentives.
Actually, with the gas prices going lower, the larger vehicles will start to become more popular again. Consumers get lulled into the mindset that the gas prices will be low for a long time and that they can now afford a vehicle like this. Next summer when the gas prices have risen back up to "normal" these same people will be "B"ing that they cant afford it anymore and want to trade it in on a more economical vehicle. Then they won't understand why the trade in value has gone down....I saw that happen SEVERAL times.
