2006 Subaru Impreza 2.5 i 4dr Sedan AWD (2.5L 4cyl 5M)
This is an awesome car. Looked at the Mazda 3, Hyundai Tiburon, Mitsubishi Lancer Ralliart, Ford Focus, and more. The Impreza is in a class by itself, and sells for about the same price as the others given the amount of standard options. Very safe car with AWD for the winter season and a blast to drive. I can't say enough good things about it. Anyone considering a sedan for under $20K needs to check this out. Keep in mind the mechanical advantage over the competition (ie: AWD and the boxer engine).
Seats -- great seats with good support; look good too. Engine -- very flexible, good power, decent fuel economy and it's smooth as silk (can't even tell the engine's running at idle).
