i am thinking about buying a 300zx but the problem is it has 140000 miles on it. how reliable is this car and how long do the engines last

 

it all depends on how well maintained it was, i had a couple of nissans that lasted 190,xxx miles before they gave up.

 

i'm with nismo it al depends on the owner and how it was maintained.i've had several the most miles i had on 2 that i sold was 235,000 and get ready for this 425,000 i was the second owner and it didn't smoke a drop,i was thinking about keeping iit and seeing if i coud break the 500k mark but i had too many toys and didn't have time to drive it that much
