If you're into compact-ish fuel efficient, you should check out the 2012 Ford Focus; pretty slick car, great interfaces/bluetooth/nav options, VERY good mileage (40+) and fairly fun to drive. +/-$20k new.

Also, the 2012 Subaru Impreza has upped the mileage significantly (34-35hwy) and is quite reasonable, with several models around the 20-22k mark.

Jetta TDI Sportwagen is a terrific car, but they're not widely available new. There's a guy in VT here who specializes in the secondary market for lightly used TDIs of all stripes; he might be worth a try if you're interested:
