Well spotted, I've just sent them an email as i'm currently paying DD instalments for my extended warranty to commence in December at £895 for 2 years, I'm fearing this is a website error as the other prices look right, unless they've deemed the warranty repair claims since it's release to be far lower than expected or the uptake of the extended warranty to be poor due to price. Seems daft to take out a warranty for a Lexus but others will say when something does go wrong the cost can be eyewatering on these, so piece of mind really. Probably wouldn't bother extending the warranty yet again at 5 years old.
Also remember the extended warranty covers you for comprehensive European Breakdown Assistance, worth £120 a year.
I have a broken demister element on the rear windscreen, will have it assessed for a warranty repair when it goes in for a service next week, if they try to wriggle out of it due to being glass I won't be best pleased as there is no impact damage, the only exclusion in the T&C's. Will be interesting to see what happens and will greatly influence my decision to keep the warranty or get a refund.
