Kinda crappy for the next owner to find out. Especially in California.

Sometimes those codes are just an O2 sensor that needs replacing. Cat really shouldn't be bad if the car wasn't misfiring or running with a CEL on for a lean/rich code for an extended time period.

I killed a cat @ 67K and fuel trims were good according to all I asked to include servicing dealership.

You've had multiple coil pack issues. Can't imagine that was not a contributing factor.
