No this tax is from the City of Milford, not the state. The state only taxes your cars when you buy them, at 6%! You can't fudge it either, I think its 10 or 7 years old, but anything newer is done by book value. So you can't buy an 03 S500 and write $10k on the bill of sale, they don't care. Not that anyone would ever do that...
