I purchased my 2007 HHR fall limited edition on July 5th. It has the spoiler, running boards, and a factory pinstripe. I've put 2000 plus miles on it in three weeks! Went to Memphis from Milwaukee and back on a road trip. I love this car.
The factory radio is nice, as well as the ability to put the back seats completely down. Plastic on the back of the back seats is nice so you don't scrape the seats putting stuff in the back.
The cupholders stink. Hard to use, especially with the arm rests down.
