You could find the semi leather seat cover from mudah, there's an accessories shop selling that.

Ertiga is a good fuel consumption compact mpv, my worst fc was 15.4km/L when everyday mega traffic jammed right before CNY balik kampung times.
Best fc was 19.4km/l, and now is 17km/l with heavy foot.
Overall it's easy to steer, NVH better than Exora and Innova. Quite decent Japanese car.
Don't worry about the torque of car, I could climb Genting easily with 5 adults and luggages. (manual)

First service fees was about Rm246 with 5w30 fully Eo.
