My IS went into Stockport and then sent to Smith Knight Fay after being hit up the rear on the motorway, just short of £4000 damage.
They estimated 4 weeks for my repair, eventually got it back after 10 weeks!!!!!!
I rejected it twice, the first time it was a disgrace with drip marks in the paintwork and a chunk gone out of my spoiler!
My rear light cluster has been re-fitted by Lexus Stockport 3 times since and still keeps falling away!
Wish they'd wrote it off!!
