Should I get it? 1981 Datsun 280zx?

This guy is selling a datsun, no rust and hasnt been wrecked. It also has a new clutch, and a 300z turbo. There is however a leak that he thinks is due to a bad head gasket... My brother had a 280zx so maybe part of it is just sentimental but, should i get it? What should I worry about with datsuns? (besides the fact that their parts are hard to find)
