I must comment on how knowledgable, practical and personable everyone is in this group who’s responded to my situation - theft of my RX450 about 16 days ago. Insurance company gave me a very fair price for my loss and I’ve returned to my Lexus dealer and bought a ex-demonstrator, low mileage rx350, registered in May 2023. I’ve asked for either assurance that the model has improved anti Can-bus security or that the retro fit is done before I take delivery - local guys are not fully informed - but they will Be!
