24: Cadillac ATS
Few cars are obscure as the Cadillac ATS is, this is a car that practically nobody pays attention to. Chances are you’ve run into the ATS at the airport. The car is a favorite of premium rental car fleets. It’s a Cadillac and should mean it’s the pinnacle of luxury, right? Wrong. The ATS is about as bland and basic as you can get and provides a lackluster driving experience as well (via Car & Driver).
The car has received minimal updates since it was released almost a decade ago, although Cadillac seems poised to finally cancel the model. You’ll likely find a lot on the ATS prices right now, but this is definitely a model that should be avoided at all costs. There are much better luxury cars that offer a plethora of better features.
