When I first originally ordered the IS250, I want something to set it apart from (most of which were currently on the road back in 2006/56)
I imported the original rear lip spoiler from Sewell Lexus, handed it over to Lexus Leicester to fit.. @ £100.
Most likely they got a third company to fit it, however I want it all fitted in time for delivery (1st Sept)
As long as its original parts should be a problem.
Fit it once and fit it right.
