Red Monster Fuel Tank for Sale

Hey all,
I have a red Monster fuel tank to fit an 2001 620i - although I am pretty sure it will fit later models (and larger capacity models) too. I bought it off e-bay as a replacement for my girlfriend’s dentented tank but never got round to fitting it. Its just sat in the garage housing spiders. It has two very small dents which I am sure can easily be sucked or pushed out. Can send pictures if required. I live in SW20. I am told a new tank sells for almost a grand!! Bargain to a good home.
