I live in the area as well. The Post article mentions a new 1% car tax on new vehicle sales, and three bills under consideration contain a gas tax increase.

No tax at all up to 2.0 liters, then $500/liter for used and $1,000/liter for new each time they change hands. Utility vehicles might get different treatment, but they have to be utility vehicles, not this minivan/SUV stuff sneaking through.
