289 COBRA
larcinese, the clean 289 originals without a marred history are as a part usually over 250K, but "bad damage/paper trail" 289 COBRAs can be had for less.
I would search for an incorrect or bad resto on a CSX22XX to 24XX car and set about over the years to make it an absolute perfect restoration.
I don't think you will be using it as a daily driver, or your insurance agent will be having mini strokes waiting for it to be wrecked or stolen. As a point the last 289 we repaired was a left front fender, left out of gear and a masonry planter wall just up and ran into it, $7450.00 repair bill as vs a $2000 or so one on new vette. Try finding the correct type Lucas headlight ring NOS!
You will find you are bidding against several thousand current possible buyers poised, ready to buy that same 289 at a good price.
