So, there is a seat dealership in the group I work for and I know the parts manager there. I asked him for the part number of the seat mii armrest (1SL061100 if anyone's interested). He said they'd ordered one to fit to an up and it looked like it would be a direct fit. I imagine it will be as the layout of the 2 cars should be near enough identical. I was just wondering if anyone has fitted this part to their up yet and was it a straight fit?
