bnewell,
I can only guess that they'd be in the mid $40k range but to be sure, contact Dean Rosen personally and tell him that you're interested. Both cobras were exceptionally nice and very well maintained. My brother and I both have SPF's and are very particular when checking out vehicles. You're more than welcome to visit either of us to see our cobras. Dave lives in Wayne Ohio which is near Bowling Green and I live in Richmond, Indiana, just over the Ohio, Indiana border.
Mike Noman who can be reached at 1-606-384-7004 lives over the Ohio/Kentucky line and has a beautiful B&B/LA Exotics that he's completely rebuilt. When we last saw Mike at The DV Spring Fling, he had just installed a new 427 and completed some cosmetic upgrades that really made his cobra look nice. It was for sale at that time, but it may be gone by now. Give him a ring and he'll tell you more about B&B than you ever could imagine!
