I am thrilled with my Blue Tissuebox. The reason I bought the SC was because it came with the armrest with storage. Currently dealers are giving cars away cheap and this was a great deal so I couldn't pass it up. I have no problem with the mileage. It gets exactly what the sticker said. I love the steering and I feel my SC is very comfortable.
I like the suicide doors it keeps my 8 year old in check, the rear seats fold up or can be removed for more storage.
The visors must have extenders. When you pull them to block the sun coming in from the driver or passenger window they are worthless. More options such as a DVD player and better stereo system. Get rid of XM and get Sirius. Probably a 5th passenger seat would be useful
