With gas under $2 a gallon, it's not surprising that SUVs are selling like hotcakes and sedans are barely moving.

Bump gasoline up a dollar or two, then SUVs and trucks will slow down.

Cars are also better these days, lasting longer. I've got a 10 year old car (had it for a year), it's been rock-solid reliable. I think good used cars are a compelling alternative to a new vehicle.
