Do you have 7 seat or just the 5 seat Sante Fe? If it is 5 seat, you have probably noticed, but there is no point in driving a 5 seat SUV to do uber with due to mileage/costs and you just have same earnings that you could get with a Prius. Santa Fe XL (7-seat) is among one of the vehicles I would consider as a replacement for my current ride, German Select vehicle and a waste to uber with. If I am going to continue ubering I might as well get a prius and do Uber X instead of driving a Select vehicle. My ride is good until end of next year, so a replacement is something I have been actively thinking about.
Note that rumours are 7seat SUVs are also going to have to take poo rides sometime after July 15th. Which makes sense, if Uber is short drivers, they will push poo to as many drivers as they can. So if that is the case you might not want any SUV to uber with, unless that is the vehicle you would want to drive even without Ubering.
As a side note, strangely enough and despite my dislike of poo, this morning I got a surged Poo that was close so I took it. Ended up getting 2 more matched surged poo rides all in one trip. Very next trip was another close surged poo, so I took it and got another matched with another surged poo. So this morning rides boosted me to my 2nd highest ever hourly/distance earnings. But bottom line is I didn't need a Select vehicle to be a poo bus driver, could have had the same earnings in a Uber X vehicle with lower costs.
