Some say the interior looks dated, I say it looks fine. Now that it is about 5+ years old, no one can believe it has 60,000 miles, it looks new. I am a very maintenance concious though. I wax every 3 months, and wash every week. I definitely do routine oil change.
A ton of power. Best in it's class for gas milage for a v8, so I won't complain. Killer dual air / heat works very well. Ride is spectacular. Radio is decent. Subwoofer adds kick.
Chevy has had its problems with power window regulators. I had 3 replaced so far to the tune of 896.00. Thankfully I bought the extended warranty, so I paid nothing. Multi CD player would be really nice, or even an MP3 option.
