Hi,
actually, it'll be advisable if you can just send in the car to the
mechanic for a check upon getting a 2nd hand car, and they should
be able to advise accordingly.
Some will say need to change timing belt at 60,000km, and the water
gasket as well. But I did mine at 80,000km and its perfectly
okie.
58,000km for a 1.5 yr old car is a bit on the high side. But of
cos, that depend on how much he is selling you also. Is it a 2000cc
version? If so, you might want to let us know how much you are
getting it at.
