I have an 03 Cobra 10th ann. silver coupe with just under 5K miles. I am considering trading it in on a 2004 F150 Supercrew Lariat 2WD loaded with most every option except a sunroof. The truck MSRP is $35,600. I can buy the truck for $31,750 and they are offering me $25K for my Cobra. Does that sound good? bad? I will have to pay $6400 difference. Please let me know what you guys think. P.S. My Cobra will be traded in 100% stock, so I will have wheels, CAI, brakes, etc. for sale....
