I've had xenons on all my family cars for at least five years now. I can't believe our 14 Limited doesn't have them standard. It would be my biggest gripe, but that is reserved for the fact that it has been at the dealer half the time I have owned it.
The stock halogen headlights flat out suck. There is no questioning that. When the dealer tells you to upgrade the headlights right after you buy it you know something is wrong.
