2001 X50 911 turbo ,

NZ new car, 4th owner however only had it serviced by local mechanic no
diognostics used, so missed a few things like failed regulator, he owned it
from 40,000km to 80,000km over a period of 3 yrs, 5th owner now has had
it for 2 yrs, done 20,000kms in it, when he got it he took it to porsche
dealership for full service and has done twice since. had gear cables
replaced, prior to having it fixed he thought there was a problem with
gearbox as it had jumped out of 2nd gear once.. but now says dealership
say it was cables. car has brand new michellins all round and has just had
full new clutch done....whats it worth in New Zealand dollars. $60,000 to
$75,000 ????
