This was (almost) my first reaction too, but in North America, California holds the title. 50% more in Taxachusetts isn't 50% more compared to most parts of the country including AZ. Sounds like the OP has friends and family connections to MA and that's worth something, but I spent some time on the east coast before going to school in Arizona and there's a world of difference between the two that I would personally think twice about. Man does not live on (heavily taxed) bread alone...
To more directly answer the original question, maybe consider selling your wife's car and letting her take the Raptor. My experience with Wife + Raptor started out as, "I will never be able to drive that thing!" to "Why don't you take my car today so I can drive the Raptor?" so don't dismiss the notion out of hand.
When it comes to “true liberalism” like what you’ll “see & feel” in your everyday life, not not just the total # of liberal politicians & policies- but what it’s like to live in the state day to day, these states are all worse than MA in that regard (Trump got nearly 1 mil votes in 2016 in MA)
OR, CA, NY, NJ, CT, VT, “1/3 of PA”, WA are all worse
if that helps at all...and I’ve lived in NY/NJ & have been in MA most my life & have traveled/worked in those left leaning west coast states a significant amount of time so coming from some experience
Also I don’t want to come off too negative, there’s lots to love about MA, great scenery, lots to do, 4 seasons can be nice....you mention having access to the cape. Whenever anyone questions MA while the wealth/real estate value/cleanliness/good schools etc are well known when it comes to Boston proper & the nicer surrounding suburbs- when it comes to a lot of the cape, and certainly the vineyard & Nantucket....well all I’ll say is there’s a reason some of the worlds wealthiest, most connected, most famous people opt to have a home there as opposed to the FL keys, Bahamas, Hilton head, etc you name it.....people that could have a vaca home quite literally ANYWHERE & instead they’ll pay $10-$25 mil for a place there....
