Thanks for replies . Best quote I have is £850 but company gets very poor reviews so think I will contact Admiral to see if they can improve offer. Did try Privilege, LV and Lexus own Insurance but all of these would not offer cover . I live in low crime area, no convictions or accidents and 18 years no claims so can only think its a problem with LC500? Could it be that insurers have seen the price of replacement parts - I guess its telling that Lexus will not even offer alloy wheel insurance when you buy it.
