wing mirror

On my hellrot 1999 bmw z3 someone kicked my wing mirrors - the right one survived (glass shattered though) and the left one shattered but the metal base/arm snapped aswell - what’s the best way forward? Glue the arm and base back together? Buy one of those plastic vases and spray it hellrot red...

Does anyone have/ know where I can get a Racing Green Z3 driver’s side wing mirror? A lovely gentleman reversed into mine at Tesco... Thanks!
