Hello gentlemen,
As usual, thank you for your input. Mikey2001 you’re thinking matches mine regarding cost. The kicker is compatibility with the ES hasn’t been Lexus U.K. verified.
Having been the ‘Village Idiot’ for 2 decades now DIY retrofitting would end up being a monumental error. So, if I’m going to do it, I’ll need Lexus mainline expertise. Plus, in the unlikely ever of a snag, I can invite them to rectify the issue(s).
Thanks for the continued support and interest in my information gathering exercise; greatly appreciated.
