Hi Chris
Incidentally it isn't! I own a navy blue one but you are right about the scarcity of Lexus cars here - I think 10 in total here would be mighty generous for my estimates :). Thanks for the tip, though! It's actually the plastic bit that's cracked (right at the base). It appears to be a small part which connects to other parts but I can't be sure until I actually see a diagram of the part or area.
I have tried to access some Lexus spare part dealers but most ask for the part name or number and I am unsure how to find this. Do you have any in mind? I did contact 247spares.co.uk who hooked me up with a couple of contacts - thing is there is only a telephone number and all seem to be engaged :(
I just want to be sure what part I need before I take any further action!
I'm sure you must be pleased to be away from the atrocious weather (although we can't really call ours bright and sunny now can we?).
Thanks again for your invaluable tips.
