| 2013 Chevrolet Spark Seat Room and Comfort: Pros | ||
| Year | Comment | |
| 2013 | Actually, just room. The firm, thinly padded rear seat provides minimal comfort. But there's more rear legroom than in quite a few larger cars. A Ford Focus, two size classes up, offers two fewer inches. Chevrolet's own Cruze offers just a few tenths of a inch more. see full Chevrolet Spark review | |
