Warranty is an absolute must IMO. Sure they are very robust and reliable but.... When something goes wrong the bill will be big. ISF extended warranty is currently £795 for two years which includes the top AA cover. I recently had my brakes fail, new master cylinder and servo, bill would've been £1,800 😲. AA cover recovered the car straight to Lexus.. Don't let this put you off, these cars are amazing but for the equivalent of £30 a month, why take this risk.... All IMO 😉
