As much as I hate to say it (owning two crossfires now) that seems high for what these are going for today
example recently here in Atlanta a 2005 SRT repeat SRT convertible went
for $19,500 with less than 5000 miles true while this is an absolute steal
in this case the Ltd convertible with your milage should go in the 12 to 13K
range other members might agree or disagree one suggustion is to have the dealer furnish you with the 7 year 100,000 mi bumper to bumpter warrantee which would cost you $2500 plus /minus but not him they come $0 deductible, $50 and $100 hold out for the zero the others are several hundred dollars cheaper this is actually 4 years and 64,000 mile added to the basic warrantee with that $16,500 would be a fair price to you but not great
