I've been doing a lot of rentals at DTW in part due to their promotion with United (5750 miles per rental). The last couple times I've done Ultimate Choice, it's all been very boring choices - almost 80% of the vehicles it seemed were either a fusion or a malibu, with a couple optimas and hyunadi's (not sure what model) thrown in. The premium upgrades have been inifiti's. I finally got something a bit nicer last night - a 2017 XTS with only 4k miles on it - really nice to drive. There was also some SUVs including an inifinti QX60 available to choose from.
