The Lacrosse CXS is fun to drive. Very comfortable seats. Lots of power from the new 3.6 variable-valve-timing V-6. Love the XM satellite radio. Good fit and finish, both inside and out. Good handling car. Much better driving and more comfortable seats than previously owned 2006 Lucerne CXL V-6. Poor gas mileage on the 3.6 V-6. Some kind of reflection appears in both sideview mirrors (suspect from bright moulding at bottom of front side windows?) Don't like GM forcing customer to buy their OnStar system. I could live without it. Rear seat leg room barely adequate. The rear view is rather ugly, especially with the 2 big tin can mufflers.
The 3.6 engine is super smooth, quiet and quick. The car has a nice tight turning radius (much better than the Lucerne). Like the location of inside trunk release on power door button. Really like the XM satellite radio and upgraded audio system.
Make OnStar an option. Paint rear mufflers flat black and cut out lower edge of rear bumper to put some big old fat chrome exhaust tips to distinguish CXS from lesser models of Lacrosse. Get rid of reflections in side mirrors. Move power seat controls to door panels.
