There are very few vehicles available today that compare directly with the Scion FR-S and Subaru BRZ twins. A case could be made for the Mazda MX-5 Miata, and possibly even six-cylinder versions of American coupes like the Ford Mustang. Pretty much everything else is either too expensive or is powered by the wrong set of wheels.
