Well mate, i dont mean to be a bitch, but if hes taking it to a rover garage, they will rip his money from his hands, they will make up alot of bullsh*t like: "As the car took quite an impact we will need to replace the whole boot lid, and the brackets, and as the light may have taken some damage we would prefer to not risk it and fit some new ones, and their casing. The bumper may be usecure so well have to refit it onto the mounts. This will come to about £700, and then £1,000,000 labour. Thank you." Whereas if he takes it to a proper normal, trustworthy garage im sure you will get away with paying a little more than £150. Honestly, the BMW garage said they had to replace our whole door bracket on our X5 as it was clicking, and said it would cost ~160 for the bracket, and ~120 for the labour so i had a look, and it was just a star bolt that came loose i did it up and it is still fine Just goes to show how much they want your money.
