Sorry but I have to vent about this one.....Registered my car in 6/2009. Excise for 2009 was $221. So I was assuming a little more than double for 2010. Just got my 2010.......$680. WTF....they doubled the value for 2010. Of course the assessor's office has some lame excuse about they only value at 50% for pre manufacturer year and now that it is 2010 and it is 90% of the actual value......Good old taxachusetts!
