Well mate, I while I was my local Lexus repairer I happened to mention I was looking for a set of LS400 Lexus badges....by the time I went to collect my car I was told I could have a set of gold coloured badges that needed to be cleaned up a little and they only cost me 2 dozen beers.
So it doesn't hurt to ask the guys on the workshop floor, or in my case it was the guy who drove me home. Because you never know your luck...!!
