I’m looking into an overall good condition wagon. 70k miles, grandma owned. The two issues that worry me, the car sat in her garage for over a year without moving after she passed away and it’s also showing an AFL headlight issue.
I know the timing chains are a known issue. Is there anything else I should be worried about? What should I look at when checking out the vehicle? How hard is it to get parts for the wagon? Do you see these continuing to depreciate or hold/go back up? Any and all info will be appreciated.

Specs:
2010 CTS wagon 3.6 performance RWD
2 owner
70k miles
Known issue: AFL error for headlights
