Worth upgrading from a 2014 Outback Limited to a 2020 Outback Onyx XT?

I have a 2014 Ouback Limited with 133,100 miles. It's in good condition and has all the options that were available for that model/year. It does feel a bit outdated and would probably be replaced in a year or so.

Anyone have thoughts on whether it's worth upgrading to a 2020 Onyx XT with 77,000 miles for ~$20k? It's being sold by a trustworthy family member. Any known issues with this model, or red flags to look out for?
