Buying my first Chevelle/Malibu

[xk49]

1964 Malibu SS (true SS) Going to take a look at this car Monday. Supposed to be a med/high end restoration(frame off). Period/date correct 327. Almost new everything. By no means a resto mod, but also not 100% original either. For the sake of argument lets say the work is top notch 9/10, running gear/suspension is addressed and body undercarriage solid(no rust), what would be a good number to reach for this car?

I've checked just about all comps on the major sites(classiccars.com, autraderClassics, Hemmings, etc. and this cars asking price is on the high side.
