Welcome and good luck with your search. I believe silver was a rare 2007 color and looks great while Saphire Silver Blue is much easy to find. You can save money by looking at other years. There isn't any real difference in the cars from year to year. 2004 had every option 2005 in on came in base and limited. For the price of the 2007 you are looking, you could get a SRT which was almost exclusively 2005. In the long run the SRT will always be worth more than a normally aspirated Crossfire. In gerneral these cars are very well built and reliable. With a Crossfire you are basically getting a great deal on re-badged Mercedes. Besides the badges and VIN number, you won't find anything Chrysler on these cars.
