I have that interior on my R-Line and I wear jeans all the time. I also do about 10K a year so it gets pounded and have cleaned the interior a grand total of 4 times. The latest being done by the VW dealers who gave it its first service yesterday.
It looks as good today as it did when I picked it up. N0 need to worry.
Current car: Mini Countryman EV in very shiny black!
Previous car: MG HS Exclusive in nice shiny black.
