"Stability and traction control put you in control. Vehicle stability control stands on solid ground. How economical is this! Just in this charming-looking 2015 Chevrolet Sonic comes with an ECOTEC 1.8L I4 DOHC VVT engine and 6-Speed Automatic. The engine and transmission are both silky smooth with perfect starts and shifts. The rest of the car is in just as good of condition!"
