In the auto industry, the term "halo car" refers to one desirable enough to attract buyers to showrooms. For Subaru, that's the WRX, a compact sport sedan that draws on the brand's history of rally racing success. The standard model is quick and subtle, and the STi fast and showy; both are good deals for the performance on offer. Handling is great, and Subaru's AWD technology makes this a formidable and fun four-season ride.
