Try Grundy. Vettes are considered collector cars there, even new ones.
You have to have another car, a daily driver, at least as new or newer than your Corvette.
They are a broker serving nationwide. In addition to Grundy, you might also check Leland West. There in LA......I know thats not close to Mass either, but again they are a broker serving nationwide. I have my coverage with Leland (underwritten by American Home). They have a restricted plan limited to miles of 2500 or 5000 per year. They offer stated value coverage. I used to live in Mass I know how the rates are there, but they are even higher in NJ. With Leland I pay about 1/3 the cost of what I was quoted by a traditional broker/agent. Good luck
