I'm going to go with what hasn't been mentioned yet.
-Honda Integra Type S [JP] (Formerly sold in the US, as the Acura RSX Type S)
All around, an excellent choice. Exceptional chassis design and handling, for an FWD car. Good power, both in terms of peak HP and powerband, while still maintaining street usability and gas mileage. Suspension design and setup allows for sharp handling and feedback, while still avoiding being over-agressive for street use. Good interior space, large hatch area, and a nice stereo.
-Acura TSX
Many of the same benefits as the RSX, but in an attractive four-door package. Once again, great motor and chassis, and well appointed interior. Very nice audio system, and an incredibly slick, sharp, 6spd manual transmisson. Several minor, but very cool, features, foremost being the innovative interior "mood lighting", which is simply stunning in person.
-Toyota Celica GT-S [JP] (No longer sold in the US)
The Integra's long-time rival. Has many of the same benefits, but trades the Integra's compact, sharp, styling, for a longer, sleeker, appearance. Interior appointments aren't quite as nice as Honda's offerring, however, it offers the legendary Toyota quality and reliability. Proven, powerful, motor, an extremely neutral handling balance, and very economical.
-Mazdaspeed6
"The everyday Evo". Surprisingly good handling, a very nice motor, and all placed in the 6's proven body, allowing for a great amount of practicality. Has an edge over the STi and Evo in this class, as it's more street-oriented, as opposed to the Subaru and Mitsubishi offerings' track-biased setup. Because of that, the suspension is more livable, and the less agressive motor and transmission tuning makes for better reliability, and a powerband that's more practical for use in day-to-day driving.
The US, sadly, has lost many cars that would fit this class, in the past few years. Many others have been moved upmarket, with higher prices, softer responses, and greater weight, causing them to no longer fit this class.
As for the CX-7... it's sportier than one might think. Its main advantage is its use of a car platform, which gives it a low center of gravity, a chassis tuned towards sporty driving, and a car-based, active AWD system, as opposed to the traditional SUV 4WD system.
