Our Sentra GXE has been about perfect. We selected it over Hondas and Toyotas because of the equal reliability yet more affordable on the used market. Just took a long trip and got 35 mpg while cruising at 75 mph with AC on - WOW. Nearly 40 mpg should be achievable at 55 mph and no AC.
MPG... lets me smile at my 450 mile range per tank. Great travel car for 1-3 people.
I'm old school - a cassette deck WITH the CD would be nice. The newer models have an AUX in jack for your MP3 though.
