I have only owned a Crossfire for less than 5 days so I will leave the technical stuff to the experts here who have forgotten more about these cars than I will ever know.
However, I will say that these cars have one serious flaw. Once you own one you will NEVER want to drive anything else. When not driving it, you will want to just sit in it and listen to the radio. I love mine so much, I am probably the only Xfire owner alive that actually does not have a problem with the cup holder.
Get the message?

Go buy one, then show us the pictures.
Good luck.
