Got $4.5 million to spare for this Montauk beach shack? The eager seller of 24 Big Reed Path — a legal eagle who wants to remain anonymous — has knocked $400,000 off the original sales price.

The home was asking $4.9 million in 2015.

As an added perk, the seller is tossing in a rare 1954 Bentley — one of only six built by British automaker Park Ward — for any successful buyer.

The 6,000-square-foot five-bedroom, six-bathroom contemporary home comes with 3,200 square feet of decking, a pool and a pool house.

It sits on 1.14 acres with water views, and can also be sold “mostly” furnished. Inside, there’s a window-walled great room with a two-story stone fireplace, and an upper floor that has two master suites with outdoor decks and seating areas.

The recently renovated home also includes a three-car garage.

Corcoran’s Joan and Raymond Hegner have the listing.
