You get a lot with the base "LS" model Has: cruise, tilt, air, tire monitor, onstar with built in phone service 1 year free, XM CD radio, electric seat 3.5 V6, remote door & trunk, electric windows, traction control, 17" tires. Wanted to go for a Hyundai Sonata but after test drive of the Sonata found it to be a dog off the line until about 20 mph, interior was nosier compared to the Impala and its trunk was very small. Can get 33 mpg at 65 mph with a v6.
XM, built powerful in 3watt phone into the onstar system. 30 calling minutes free for two months, can add 100 min good for year for $15. V6 spunk off the line. Room and ride
Style is dated, only has 2 cup holders. LS does not have a lay down seat back or built in armrest. No spoiler, but easy to add a painted one from eBay. Have to stay subscribed to Onstar after the free year to use the built in phone.
