FWIW & IMHO:
you might want to do a search on "Sylvania Silver Stars". I do not think that there are too many good, quality manufacturers of headlight set-ups for our cars. I installed the Sylvania Silver Stars on my car last year, and although not HID'S, they seem somewhat brighter and they are bluish-white to white in color and definitely stand out in the crowd. About $ 25 each unless on sale, which generally is about $ 20 to $ 21 each. I don't think that anybody is making HID'S for our cars, and I don't know of any body selling a kit that allows you to install brighter bulbs like some of the aftermarket kits for other cars.
I also would like to know if there are other alternatives for our cars, though.
