I did a national search of Supercharged Monte's and there are only 48 listed on Cars.com. If you do a search for the SS models 2004 & 2005 there are 1447 for sale.

This is a pretty neat web site if you did not know about it. I use this one and Ebay Collector Carsalot for dreaming!

 

I've used cars.com to get specs on various cars/models. Very helpful site.
