this survey Ford put together provides some direction of what to expect:
The pricing survey reveals what is expected to be the MSRP for key options, for instance, the popular “Sasquatch Package,” which includes 35-inch tires, with 17-inch Beadlock Capable wheels, front-and rear-locking differentials, Bilstein position shocks, a 4.7 final drive ratio, and high clearance for fender flares. The package is standard for the Wildtrak and First Edition and a $4,500-$5,000 option for all other series. The move from the standard manual 7-speed transmission to the 10-speed automatic is $1,600 on the Big Bend, Black Diamond, and Badlands and standard on all other series. Upgrading the base powertrain from the 2.3L EcoBoost to the 2.7L EcoBoost is a stout $3,500 and requires the 10-speed automatic upgrade on the Big Bend, Black Diamond, and Badlands editions.
From a body style perspective, the price premium for a 4-door is $2,495 over the 2-door for the Big Bend, Black Diamond, Outer Banks, and Badlands; the Base model is an aggressive $4,700. For the buyers of the First Edition models, the upgrade to the 4-door model will cost you $4,195. The Jeep Wrangler from Italian automaker Fiat charges a 2 to 4-door premium ranging from $3,255 to $3,745.
Most other features and prices are shared with the Ford Bronco 2-door except for the choices offered for the top/roof. With the added two additional doors, the upgrade from the standard black standard fabric soft top, it will cost $700 for a Molded Hard Top in Carbonized Grey. For a Shadow Black Molded Hard Top with removable rear glass, you will spend $1,900.
