I think you mean whole car?
I have not read the warranty terms, but I won't be surprise if they void the warranty after accident (talking about major accident, bumper scratch not included). You know la Malaysian people, if they know that it's cover, sure they abuse the warranty.
Say involve in accident, and damage the engine, air-con, side mirror etc.... for sure they repair the visible part, and the hidden one like air-con will claim for warranty. Ethically, that is just not right.
But bumper scratch, or accident that doesn't affect most of the car, the warranty should remain valid. As long as you don't report the accident, and didn't claim the insurance, the warranty should remain valid.
By the way, I'm considering Saga, (not yet an owner

). But I need more points to convince myself.
Monthly installment =
((Car price - down payment) x
interest x
years of loan +
(Car price - down payment)) /
years of loan / 12
Yes, whole car.
My car just came back from workshop few days ago. The accident involves the bonet , bumper and back light. I claim the insurance from the person who knocked my car. Waiting for the repair is terrible until I tell the workshop that if they refuse to repair, I will send to proton and ask them to claim from the insurance because its 4 months+ the car not been repair after the accident.
