I took deliverly Dec 31st of an ATS Performance Edition 3.6 - couldn't be more pleased. Mine's Glacier Blue with Black Leather. Over the first 1735 miles it's averaging 24.6mpg which is 2.6mpg more than the EPS estimate. I've upgraded to Lloyd's 48 oz nylon mats - seriously recommend them. I changed out the wheels @ Discount Tire a set of their MB brand chrome and am very pleased. I ordered and received a dash upgrade kit in brushed aluminum which matches the interior. I've not installed yet, will do so Monday. Mine is rare locally as it 's not seen in any numbers on the street - yet. One close friend has an XTS Platinum Edition. Another friend is considering changing out his LaCrosse for the coming CTS when it's available. Hope he does. Now won't that be a fabulous picture - all 3 new models together.
If you can stand the horrible music, go to the GM website and click on 'Company', then 'Investors', then 'Sales and Production', then 'Deliveries'. You will see that they sold 3300 in February, and 6100 CYTD.
