As far as I am aware they (Lexus) do not offer warranties if the vehicle is 7yrs or over. You can get a warranty from Warranty Direct but I do not know how good they are compared to the Lexus extended warranty. I asked my local Lexus Service Manager to advise me on how good Warranty Direct's cover was but never got an opinion. Warranty Direct's premiums are about half that of Lexus' and you have a choice of whether you opt to have any works carried by Lexus or an Indepedant ie. if you opt for works being carried out by Lexus the premium is slightly higher. I think you can bargain hard with them as they qouted me over £300 for my IS200 but that subsequently came down to about £280 with any required works being done by Lexus. Of course the premium will be even lower if the works are not carried out by Lexus.
