A little less than that but yes thats the theory that Ive been using
Ive had an RX300, 3RX450h, 4RX450h, UX300e, IS300e spanning over 15 years now. The only problem I had was the IS300h infotainment dying after battery change. Repair bill £4k. An email to Lexus UK stating that I have been a long term customer, have a car with full Lexus service history and expect the infotainment to last the lifetime of the car rendered a repair bill of £500 - Bloody bargain!
