WIW? 71 Firebird Formula 350

[BBBluey]

So I came across it with the opportunity to buy but not sure what to pay for it. By VIN it's a true Formula 350 all matching #'s. It is running and driving, supposedly with a rebuilt motor and trans but no receipts to prove it as it was done some time ago just prior to being parked for so long by prior owner. Additionally, I'm not sure what it's going to cost to restore it/getting rid of the rust + paint & new interior = to the point of using it as a nice daily driver. I don't want to invest more than $10K in restoring it and keeping it full stock (yes I'll change the wheels/exhaust/spruce up the motor). Does that seem doable if I pay a shop to do it? As I said, DD not a show car condition.

Appreciate any advice. I need to give the gentleman an answer on it.
