Bought 5/1/2006 with 25k miles (yes, 25k). Had to get A/C compressor replaced (normal for age) and replaced a malfunctioning EGR valve. I was aware of the issues before purchase. I bought the car for $4,300 and I considered it a decent deal despite the fact that it's a Neon. I've put on 14k miles since purchase without issue. The oil is relatively clean after 3k miles (mixed hwy/city). The shifter isn't the most confidence-inspiring one around, but I've driven much worse. I averaged 28-32 mpg between May and November, but once the weather got colder my mpg dropped to 25-28 (also let my car heat up for 10 mins in mornings). Significant interior noise and rattling.
Great gas mileage, despite significant decrease in the colder weather (normal). The car has strong acceleration if you drive it at higher RPM, but anyone shifting before 3k will get poor pickup in the next gear. Comfortable seats, spacious rear seats. Alloy rims. Good fact speakers.
Better road noise dampening. The windows fog very easily, and the rear defrost works poorly. The tail light gaskets leaked water into my trunk and I had to re-seal them. No issues since. Shifter seems cheap, suspension very taught (normal for the sportier ACR's, a good thing for cornering though).
