Don't waste your energy, someone reversed their Hybrid Lexus in to the rear wing on my XF the other before driving off, very big dent - they must have known. A witness kindly supplied their details but sadly lives in Singapore. Insurers made contact, other side denied, insurers won't push because they can't get the witness to court.
Like a mug I let the repairs happen before we established liability and consequently have a higher renewal premium.
I could let the rage consume me but you know what? Some people just are grade 1 pots of toss, life is too short to let them get you down!
