Do you mean P1 Saga 4AT ATF fluid change at 20,000km interval? That is truly unacceptable. Toyota gearbox, they stated oil change at 100,000km while many uncles don't even bother to change and the gearbox still in 1 piece after 200,000km.

As long as it's CVT and no valve timing, I would avoid. Valve timing is compulsory nowadays and must have dual VVT for newer cars. Without VVT is like no fuel injection back in 90's end up high on FC. Today's cars are much heavier than back then and VVT especially dual is the answer to overcome size + weight problem without compromising FC.

Later tech, it will be compulsory for GDI + Turbocharged.
