Remember: Any car new or old needs maintainance which should not be ignored.
And do not wash baleno's engine.
Get opinion of 2-3 good mechanics if you cannot inspect the car your self.
Check list should be
original documents
original plates(for sindh)
Paint condition
Is it involved in any major accident
Is there any rust inside or outside
engine compression
head gasket(for heating issues)
suspension
Coils (specifically for baleno)
@other members if there are some other points which I missed please guide our forever alone guy:P
If the condition is good then you cannot get anything better in such price range.
