From what I hear, Prodrive does not make the UK300's anymore for the 02/03 Imprezas. The only place I see them these days is on the "for sale" thread on this site. Here's a pic of my wagon w/ them. I'm running Hella HID ballasts w/ 4300K Philips bulbs. They rock!!
Good luck w/ whatever you choose to do. Oh yeah, I recently saw a guy from RI selling a set of morrettes for $325 in the for sale thread. Check it out.
