There are only two changes for 2021. One is the Co-Pilot 360 which are the existing safety items + the S&S package. Nothing new here as the features have been around for quite some time. Some consider them doo-dad's, other consider them to be essential. Your mileage may vary.Although I did see yesterday that it looks like 2021's have a lot more tech in them and I'd rather mine have as little extra doo-dads as possible.
The other new feature for 2021 is a front and rear Belt Minder® safety belt reminder system and rain-sensing wipers. So no major changes. Still your decision as to which was to go.
By the way Cobra Jet has a thread on buybacks. It's an interesting read. You really have to stay on them. Daily if necessary.
