I have been driving this new 2008 Impala LS for one week. There are a lot of improvements over my old 2001 Impala; mainly in the computer area, not mechanically. Overall, this car has good value. The LS has power window, lock, seat, and steering; cruise control; keyless entry and trunk release; OnStar; and XM radio. All these in the low end LS model! I just hope that the lower intake manifold gasket will last longer this time. Try to make a spare key (to open driver side door) in Home Depot, no luck! Home Depot does not carry this new style of keys.
Keyless entry; OnStar; center located shift stick; power seat; large grove compartment; roomy trunk; styling.
Side mirrors could be bigger; look good but not practical. Uncomfortable rear seats; too low and no leg room. Front passager seat belt could rub against plastic siding, causing rattling noise. Gaskets on all 4 doors have a slit at the bottom (for water escape?), they will tear eventually.
