I have been driving my Neon SXT since 2002 when I bought it and have YET to put a penny in to it, other than tires and brakes. The gas mileage is incredible. With today's gas prices, I put $15 in my tank and get to and from work for 4 days, and it's a 30 minute highway drive. As far as the interior comfort, I am 6' 7" and fit surprisingly comfortably. Most controls are easily accessible, except maybe the cd changer. The exterior, despite your normal dings, still looks good. I still look at it after a good wash and wax and think "wow, looks pretty good". My overall impression is a positive one. If you keep up with routine maintenance, this car should be good to you!
The fuel economy! Gas is currently over $4.00 per gallon and I haven't felt the strain!
The front windows are power windows and the back are manual... why not all power?
