It's a high price but if you really want an SS and have the disposable money for it why not. For those of us who have spent countless hours attempting to rid our G body of rust knows it's still there. At least with a car in showroom condition you can use the products that work to prevent rust.
I think there is definitely is truth to that. I think in many cases its more cost effective to buy a well preserved car then an initially cheap rusted one. Not this well preserved though, Id say get a 6-8k 50k mile car.
