Old car with good condition. New car would be better.

The car that I rented is a Toyota Yaris Ativ, I didn't expect them to give me an old year Yaris Ativ, and there is no parking sensor on this vehicle. However, the car's condition so far so good. I was late to return the car as I needed to drive 2.5 hours from Hua Hin to Bangkok. The staff can't stop calling me and telling me I need to pay the extra charges. I already told her I have no problem paying extra fee, but still receiving their call on the road. So annoying.
