I may be a bit biased as I inherited my mom's 1984 RX-7 as my first car. It was light on its feet, smooth, high revving and nimble as a go cart - so is the RX-8. The car isn't super fast, especially from a dead stop, but it has lots of pep and is plenty fast as long as winning drag races isn't high on your must-have list. The handling is wonderful and the car looks great inside and out. The nav system can fold away if you don't want the screen to show, and the Bose stereo can get painfully loud. This is the first car where I can't stand to turn the stereo to max. Negatives - fuel economy is SUVish and the car gets hot inside from the engine. The A/C can barely keep up on a hot, sunny day.
Smooth engine, handling, classy looks.
Fuel economy, under 6 second 0-60 that is achievable by an average driver, stronger A/C.
