Cost
The destination charge is a standard charge for transporting the vehicle from its point of origin to the dealer. The Dodge is substantially cheaper to get to the dealership than the Porsche Cayman S.
The Dodge Challenger is tremendously less pricey than the Porsche Cayman S with respect to MSRP.
Utility
Drivers with frequent kid-duty might favor the Challenger over the Cayman S.
Dimensions
The Porsche Cayman S's tank is roughly the same size as the Dodge Challenger's, though the Challenger's is somewhat larger.
Performance
With that kind of horsepower, both the Porsche Cayman S and the Dodge Challenger are legitimate sportscars.
Overview
The basic after-sale protection that comes with the Dodge Challenger isn't quite as generous as the Porsche Cayman S's.
