I drive city for uber grab & this what I can tell you.

1). Fuel consumption - just ok ok only but can be better if drive Axia or Myvi.

2). Maintenance - expensive! 10k km is just between 2 to 3 months only. If hardcore full time driver, maybe need to do maintenance every month.

3). Rider comfortable - the car is very comfortable for uber grab but most riders didn't appreciate it & some will still give u low rating no matter what especially those on short distance & fare between rm3 to rm6 or those using promo code. Sad but true!

4). Conclusion, if u have other choice, just use the cheapest car like axia, saga or myvi. Riders usually don't appreciate the ride.

Yeah, it's a waste to use mid to high end cars for uber grab but if no other choice, still have to do lor. Personally, I think with the fare & income you get from uber grab, better use cheaper cars as it's not worth it to drive cars like city in the long run.
