I bought a Seat Tarraco Xcellence a long while back. It took more than 3 months to get build. Due to this I was one of the first to get a german version of the 2021 edition.
Thank you. The colour has the german name "Delfingrau" which would translate to "dolphin grey" in English. I'm not sure if Seat simply translates colour names, though. It is a grey with a very slight blue tint.
