My advice is to start with the best reasonably priced example you can find. Mechanical parts don’t seem to be too expensive or hard to find but interior parts which are exclusive to the crossfire along with some exterior trim/body pieces can be harder to find and command hefty price tags. I bought a 2004 Limited with 36,000 miles four $4200 but it was missing a couple of pieces, had been neglected and had a mouse living in it when we brought it home on a trailer. I’ve been able to source most of the parts I’ve needed with the help of forum members, salvage yards or eBay. There are still a couple of interior pieces that I have not been able to find or could not justify the cost of and depending on how nice you want your car to be these things can add up quickly. Paying a little more upfront for a nicer specimen can pay off in the long run especially if you can’t do all the work yourself.
