Florida doesn't have weather, though. The salt along with cold + hot temperatures wreaks havoc on the roads. How bad do you think the roads here would be without any tax?
Regardless, I think MA uses a quicker depreciation model for the excise tax. Next year's bill should be quite a bit lower. It hurts a bit when you're used to a $100 excise and get one for 5x that. At least my bike was only $15
