Good deal or nah?

Found this beat up, but beautiful 1966 Ford Mustang coupé in our neighborhood. It's installed with an 289 V8 engine now. It comes from California and supposedly did not run for about 15 years already. On the exterior i can do everything by myself. Internally i'm not that familiar. The asking price is 9000€ in The Netherlands. Is it worth to go and take a look at it and give a try to restore it? Anyone got tips what to look for in the specific car / engine or stuff that i need to take into account? Thanks!
