At first glance, the Chevrolet Spark might seem like an odd move for GM after recently releasing its entry-level Chevy Sonic, according to Cars.com Industry Analyst Kelsey Mays. After a closer look, the differences are stark. The Spark is much smaller compared with the Sonic, and its interior isn’t as nicely appointed. The small footprint doesn’t leave much room for cargo, which means you’ll have to fold down the rear seats to move anything, and folding the seats is a surprisingly difficult thing to do.
