I have another question for those in the know (sorry for all these...):

In terms of the timing chain, I am aware of the issues they had so I won't be buying a car unless the timing chain has been replaced. However, beyond that I am not sure what exactly I should be looking for in terms of this issue. I assume the preference would be that the chain was replaced as preventative maintenance, rather than after failing? And am I simply looking to see that the chain has been replaced, or is there any other work that you'd expect to have been done at the same time to prevent future failures that I should also be looking for?
