Apologies for commenting on your LS400 forum, nice to know we're all welcome. Won't make the same mistake again. I wasn't trying to offend you or belittle your comment. Was just having a laugh over the Rolls Royce comment, was meant to be light hearted, sorry. I'll take myself and my "wee" IS back to the IS forum and leave you to your obviously more superior Japanese Rollers that require £80 coolant.
I was just relaying information I'd been given from a Lexus dealer that's all and trying to save the OP a few quid.
