Even though the base Impreza is often overshadowed by the hotter WRX, it is one of the only affordable AWD cars sold for under $20,000. On snowy and slick roads, the advantages of AWD are obvious. A powerful 170-bhp 2.5L flat-4 gives the Impreza an edge over most other competitors. Transmissions available include a 5-speed manual or 4-speed automatic. A comprehensive set of standard features makes the Impreza an excellent value.
