The Corolla has good cargo space and comfortable front and rear seats. It comes with air conditioning and a four-speaker stereo, which is decent for the class, but some of its competitors also have an auxiliary input jack and power windows and door locks on the base model. Higher trims and option packages add power windows and door locks, keyless entry, cruise control, steering-wheel mounted Audio, Bluetooth and cruise controls, navigation and an upgraded stereo with MP3 playback capability and satellite radio. The Corolla has lots of standard safety features, like electronic stability control, traction control, anti-lock brakes, electronic brake-force distribution and brake assist. In addition to all of these features, the Corolla has above-average crAsh test scores. Its reliability score is also one of the highest in the class.
