Thank you for your reply,
I have owned 2 citys over the past 7 years, with the L13A and the L15A, one of the main factors that destroys these city engines is over heating because of having no gauge for the temperature and eventually resulting in an engine that becomes noisy. The crankshaft is the first engine component that needs to be replaced.
If you can squeeze 150k kms from an auto, I would say that she served you well,
Here is an advise to all city (auto) owners or any potential buyer, listen to the sound of the engine or pay some mechanic to do it for you, and if you can, install temperature gauge.
