The Lexus LM running cost picture depends most on fuel or charging use, tyres, insurance and the chosen variant price. The available running-cost clue is 2025 500h Standard 4 Seats: NiMH battery; 2025 350h Standard 7 Seats: NiMH battery. Lower energy use helps in daily commuting, while a sensible purchase price keeps insurance and financing easier to manage over the ownership period.
