http://MattMazzeiChevrolet.com/2017_Chevy_Impala_near_Clearlake 707-263-0500 The 2017 Impala's portfolio starts with its roomy interior. This is one of the main reasons to consider this class of car, and compared to a typical midsize sedan, the Impala gives rear passengers plenty of space to stretch out. There's also a big trunk that can hold up to 18.8 cubic feet of stuff. Should you load up both the rear seat and trunk for a road trip, the Impala will keep your crew comfortable with its impressively smooth ride over bumps and low levels of wind and road noise on the highway. This is a restful, serene road tripper on long hauls.
