hi everyone im new to this forum. actually, this is my very first forum ever joined. for all is-f owners what type of maintenance costs are you looking at yearly? does lexus offer some kind of service for the first 4-5 years/ 45k miles like bmw? if not, how much am i expecting to spend on maintenance only? for example, oil changes? tires i can figure out, filters? transmission fluid flush? i mean since this is like lexuss' "M" version of their cars, should i be expecting hefty maintenance cost? thanks in advance for everyones input. i just dont want to purchase a car w/o knowing if i can afford maintenace cost. thanks again!
