I think that these Neons get a lot of negative publicity because of the Toyota/Nissan/Honda owners out there. For a used car though, I would rather buy a Neon for $4,000 than an Import for $7,000 any day. You can't beat it for the value and the more I drive mine, the more I like it. Mind you, it isn't worth buying new and if I did, I'd buy the Honda Civic but resale value works in favor of the used car buyer too, and I lucked out with my Neon. I would definitely buy the Used Neon over the Used Civic any day.
The seats are extremely comfortable for a low-end car. It is very roomy and feels much better than it really is. It also rides and handles nicely, and has decent acceleration. Very good car for the money (very good car anyways, even if money isn't involved)
Gas mileage. In its defense, I drive in LA and I only live about 1.5 miles away from work (I need to buy a bicycle). I think it would do much better on the highway.
