Thanks for all the replies,
This is the only 300zx I found with low mileage and good looking black exterior in the past 3 years.
Also very important ,the steering wheel is on the left side.
If I would import a car this would cause problems as they are all right side steering.
BUT as stated I can not take the risk having a busted engine, the reason why I thought it was attractive was the low mileage and first owner offcourse.
My guess was replacing the turbos and brake rotors for about 2500dollar +-(2000 euro) in parts , and do the work myself with a friend.
Anyhow thanks for putting me back on the ground ,I was floating away with joy but understand it is more sensible to wait.
