What I am aware of is that 3yrs, 36,000km means whichever one gets used up first.
I will help you with the math ok? 8000km = 5000mi. or 1,666 / month. On an annual basis that is 20,000 per year. So you would need an extended warranty. I bought a Ford 125mile / 7 year warranty for 1000 bucks. I financed that warranty and it increased my payment about 10 dollars. It is also transferable if I sell the car. It is bumper to bumper covers everything.
Again what kind of car needs 300 per month in maintenance?
