Rio EX hatchback I reviewed in December. With that being said, the SX also has the more attractive and distinctive 18" wheels and tires.
This car is loaded: Nav, heated seats, backup camera, sport suspension, six-speed auto, and a lot more, and it's just a tick over $20K—sounds like a good deal to me. Plus, with 30 city and 40 highway MPG, it's frugal. Initial impressions are that it has more personality than the Rio EX, and it's quite posh for what it is. I really like the looks a lot. More later.
