I have the parking sensors, and, TBH, they're kind of worthless.
1)There's no visual sensor (like on MB/BMW/Lexus/VW/GM) where you get some kind of icon or light to show you how far away you are.
2) The sensors go to full-tone (i.e. you're gonna hit something) when in reality there is 12-18 inches to spare. I'm all in favor of being extra cautious, but when you're trying to fit it into close-quarters, especially if you don't have a choice, having the sensors go off at 1 1/2 feet before the object is useless for actually parking.
3) The sensors are slow to react; for example, they take about 1-1 1/2 seconds before recognizing a newly-entered object into the sonar range, like someone walking behind the car or debris blown in the way. That's a bit slow, IMO.
4) The sightlines on this car are very very good. This car has very few blind spots when parking, so the sensors aren't really necessary. If you're REALLY concerned about seeing behind you, do what I did and buy a set of stick-on, convex mirrors to attach to your wing mirrors. Similar ones to these cost me $15 at autozone, although there are cheaper ones out there. Cheap example:

Basically, don't get the sensors. You don't need them.
