Then whoever buy must be very stupid. Basically you going to pay for the huge maintenance fee (coming your way).

Someone enjoy - wear and tear the car.
Another one buy 2nd hand and pay for damage?

I dont understand why people want to inherit the maintenance cost by buying second hand car.
Its cheaper, YES - but you will pay it back in maintenance which negate the saving.
If got cheated (many hidden wear and tear) and swapped (not ori) parts.

2nd hand car is not dirt cheap. It still cost a bomb and that come with the maintenance cost that come your way.
Unless you got the car from family that doing good maintenance.

power plant for most of their operation uses fuel gas - cheaper and higher MW load.
So its still consider saving to a lesser extent.

Fuel oil are nasty for power plant - lesser efficiency and fuel gas/oil changeover is not desirable - prone to trip/problem. TNB will rage.
So fuel gas is used most of the time.
