Somewhat surprised no one has mentioned the Focus. I've had 2 - first a ZX3 Premium, now a ZX3 SVT. These are outstanding cars, and outstanding value. They also have very high crash ratings for their class. The ZX3 Premium got about 34 MPG highway, the SVT gets about 28.
I highly recommend either one! These are very practical, affordable vehicles. I'm amazed at how much stuff I can get in the back of these with the seats down. They drive and handle GREAT, and are just a hoot to drive. I bought the premium new in 2002 for 13,500, you can get a used one for much less. The 2003 SVT I got recently for 14k.
I have a 65 mile round trip commute each day, these cars are FUN and COMFORTABLE! And easy on your wallet at the pump. I put 65k miles on the ZX3 premium before trading it in without a single problem, just routine maintenance (oil changes, air filters). I've only had the SVT for 3k miles but no problems yet & it's still under factory warranty.
FOCUS FANATIC!
