to each their own but i think a lot of the features of the 6WB don't get noticed until ownership and have clean they are implemented. like the speed limit in a given zone is clearly indicated and your speed above or below that with blue or red highlight in the speedo. how crisp information is. how the different modes are represented with drastic changes to graphics and colors vs having almost no idea who mode you're in on a 6WA or otherwise if not for a simple lettering. i'm not crazy about new tech but the 6WB was a huge upgrade in the cockpit experience.
i took all the hassle of making mine work in a new car by clearing the EPROM already so it's just ten minutes to swap and code it and you're done.
