Greg, most are in terrible condition tho. Your dad imported his car himself using his own contacts.
The majority are rooted quite frankly and those that think a few K fixes up a $17-20k GTR are kidding themselves. Transfer cases, gearboxs, turbos, 15 year old tired engine internals, suspension, body, interior - pfft forget it. If you are happy with a substandard vehicle then yes its fine.
that said - yes your dads car is damn fine!
