2010 Chevrolet Impala LTZ 4dr Sedan (3.9L 6cyl 4A)
The 2010 Impala LTZ is overall a wonderfully designed vehicle, inside and out. Operation of the car is very intuitive and sensible. The LTZ has good lower lumbar support (unlike the LT); however, the head-rest is TOO FAR FORWARD creating neck pain, especially on long drives (it is a mystery as to why the headrests on cars are being pushed forward to unnatural and difficult positions). The car is responsive and powerful; however seems to have less responsiveness and pickup than the LT (another mystery), despite a theoretically more powerful engine, dual exhaust, etc. Onstar is SPLENDID indeed! Sunroof inside shade does not open up the full way (to enable full exposure of the sky-window).
All control buttons and features - very easy to reach and operate. Really sleek and nice design inside and out. The OnStar is extremely helpful, though it is challenging to get up to date or accurate/proper traffic reports. LTZ has good lower lumbar support. Excellent performance and reliability.
MOVE the HEAD-REST BACK to the position where it is on the 2008 Impala LT - Do NOT push it forward in an unnatural way shoving head forward! Enable inside sunroof shade to go all the way back to uncover all the glass. Eliminate outside side-runners-are just dirt-catchers. Make avail without spoiler.
