My spoiler was supplied and fitted by a very good trader on here, sadly no more trading. I am known to be an unlucky customer.
Spoiler 1 fitted by their body shop. They then noticed it was damaged.
No problem, another spoiler was unwrapped. It didnt have the correct base. Spoiler 3 was then merged with spoiler 2 and it was fitted and was fine. No additional cost and a days work to complete a simple fitting task.
I never fit things to my car but maybe thats just me.
