G3's lens is the main problem, it's not up to the mark, I'd never pay 14-15k for that.
The morimotos are even available less than 100 at some online stores.
Retrofit isn't overpriced if you think about it, G3's cost around 14-15k, and a couple thousand more is enough for a good retrofit actually with decent projectors, bulbs, ballasts, shrouds and converters.
