Just for kicks, I pulled into a Cadillac dealer's used car lot a couple of weeks ago next to a 2006 Solstice. The salesman came out and I told him my wife was interested, so he gave me the song & dance. At the end, I asked him :
"Why are you asking $18,500 for a car that is not even close to my 2005 Xfire which I paid $15.5 for 2 years ago?"

Here's some things I noticed :
The top is MANUAL !!!
There is NO trunk.
The seats are uncomfortable.
It is very hard to get in and out of.
The transmission was an auto, but not Tiptronic.
You can only get a 4 cyl engine.
The mileage is about 22 at best
