The fifth home in this week’s roundup of Massachusetts’ most expensive home sales is a good match for a gearhead. Located on a promontory a stone’s throw from Cape Cod, the house – sold by an LLC controlled by former Alexion Pharmaceuticals CEO Ludwig Hantson – comes with a 10-car “showroom” garage that can take something as big as an RV, according to the listing. For your daily driver, there’s still a separate four-car garage, to spare you from the anxiety of a guest dinging your vintage Porsche or Ferrari.
