I have a Red Cooper (with Chili pack) but I'm looking to maybe add a few little items to it to spec it up, if possible. Is there anything fairly straight forward I could add to the car?

I'm happy with the wheels and don't want to stray from original Mini stuff but any interior or exterior OEM upgrades or enhancement suggestions would be appreciated.

One idea I did have was to get the white roof and mirrors vinyl wrapped in black, anyone got experience of this?

NewMiniStuff are good for ideas:

or Chromeline interior maybe?
