My uncle signed for Uber with 2007 model (2008 reg) xli 2 months ago at their event.
He drives 8 hrs on average (4 in morning, break in afternoon, 4 in evening)
Signup process was highly disorganized. He required valid license, car reg book, police clearance certificate, and id card. Same day his account was made and he got the first ride.
Maintenace and fuel is his own. He is satisfied but sometimes money transfer from uber takes 1 week or more in his bank so first month he was upset but now okay. He is earning about 50-60k and now planning to give car to driver.
One friend of his is using 2 drivers, netting 110000 per month car is driven for 20 hrs daily.
