I'm not a car export i just explain my personal view on it.
If you drive the car more then 250,000 kilometers properly that's the time to say good bye to your car and there's definitely a tipping point where fuel costs start to add up significantly when you consider whether or not it makes sense to continue driving an old gas guzzler versus a newer, more fuel efficient vehicle, especially if you do a lot of driving!

I think my comment might help you out

thank you.
