unless the car itself came with HIDs it doesnt matter for shit that you can get a car with optional HIDs, the reflector/projector that is in the car currently is made for a halogen, so plugging in an aftermarket kit will glare, it will not be the same as the same car that has HIDs from the factory. In my supra i retrofitted projectors from a bmw x5 so i had a beautiful cutoff. That being said, I do have an ebay kit on my vette, its 6k, i asked for 4300k, but i got a 6000k and didnt bother sending it back. Im not a hypocrit, i know my kit glares, but i dont kid myself and think its as good as a stock setup
