Could be better but age has something to do with that.

2006 Chevrolet Impala LT 4dr Sedan (3.5L 6cyl 4A)
Purchased a 2006 Impala in December of 2012 at 67,000 miles. Pulled the service history from Chevy and found no major issues in the vehicle's past. Someone ripped the connector off the rear window defrost so that needed to be re-attached. This Impala had the factory fluid in the transmission causing the delayed shift issue common to these. Managed to eliminate that with a few transmission flushes, additives, and filter changes. Had to replace the lower intake gaskets as the engine was leaking coolant internally. Somebody tried to fix that with a few bottles of stop leak so the coolant looked like mud. Head gaskets have some external oil leaks but I haven't replaced them yet.
Remote Start. Oil Life monitor. Compass.
Holy Gaskets.....GM needs to improve gaskets. Transmission improvements need to be made as well. They destroy the fluid and turn it to sludge. Similar Toyota transmissions seem to get double the life from the fluid.
