Having been considering buying an RX the canbus fiasco has certainly put me off the brand, I was interested in one recently as the alternatives have different potential issues particularly as a long term ownership prospect .
So, autotrader has a Lexus RX 450h 2022 premium pack, 10k miles at a main dealers at around £37500, tried the part ex trade in price estimator for that car, looking at a hypothetical PX to an RZ, Asking price £55K, again at Lexus main dealer, their best trade in price that they would offer £28500! So simply buying the car I'd loose £9k as I drove off the forecourt. Makes you think.
