I agree with Kelley.. if you think you might one day want to put on the SS hood, then find one soon... I'm insure if those original hoods are dated, but I'd guess that they are.. so I'd recommend checking that out as well first..
But.. if you like the car as is, and the paint is good, and the cowl setup is nice, then I'd just look for a hood (low priority basis - meaning when you find the right one at the right price, but it and store it away), but I would not change the car. It's a gorgeous car, and looking across the cowl hood, and seeing that flap open when you press the 'go pedal.. is a good thing..
