New to the HCH III
 

I'm considering buying a 2013 with 230K miles. High miles can be looked at as a negative and also as having a positive side. Was the warranty on the lithium batteries actually 15 yr/150K? How do the ICEs hold up. With that many miles in 9 years, probably a fair amount of highway driving. Maybe 70-75 mph. Will the ICE tolerate this and hold up? Any history of excessive oil usage after x miles? Any other concerns with the ICE? Timing belt/chain issues? Other scheduled major maintenance?

Any advice on things to look for would be greatly appreciated.
