Sporty cars are designed to provide better handling, acceleration, and a more responsive drivingexperience than a typical sedan. But, even within this select group of cars, performanceas well as price can vary. Consumer Reports provided road-test scores and prices for the following12 sporty cars (Consumer Reports website, October 2008). Prices are in thousandsof dollars and road-test scores are based on a 0–100 rating scale, with higher values indicatingbetter performance.Car Price ($1000s) Road-Test ScoreChevrolet Cobalt SS 24.5 78Dodge Caliber SRT4 24.9 56Ford Mustang GT (V8) 29.0 73Honda Civic Si 21.7 78Mazda RX-8 31.3 86Mini Cooper S 26.4 74Mitsubishi Lancer Evolution GSR 38.1 83Nissan Sentra SE-R Spec V 23.3 66Suburu Impreza WRX 25.2 81Suburu Impreza WRX Sti 37.6 89Volkswagen GTI 24.0 83Volkswagen R32 33.6 83a.
