Thanks for your responses guys.

I think im going to stick with the 128's. The 239's look like a larger version of the MV spoke 20" wheels that come with the M Sport so at least it will look slightly different. Whenever I get a new car I always start off well with cleaning it but over time I think ill get fed up of trying to clean the 239's so thats a big factor for me also.

I can't wait
