Because of the lack of proper maintenance PRIOR to the OP buying the car, it is no longer running. Per MA law, the OP has 7 days after purchase to have this inspected at a State inspection facility. If it fails (and it will fail) THEN the OP has options towards resolving this with the seller, up to and including "undoing" the sale.but it would pass inspection (presumably) when it was sold. The buyer failed to have it inspected when it would still pass inspection therefore, still, it's on the buyer.
This is all ASSuming that the belt wasn't changed at the proper interval. What if the belt was changed 10,000 miles ago? We don't know, do we? But, it doesn't matter, as it wouldn't change the legal rights of the OP.
