I've just PX'd my 182 (black gold, both cup packs, 05 reg, 49k miles) for a new CTR - Honda dealer came in at 5,250 but managed to get him up to 6 grand. Possibly a bit under the odds, but I LOVED the CTR! 182 was in pretty good nick, although a couple of kerbed alloys (oops) and both fog lights needed replacing...
Worth noting that the same morning was offered 7,200 by a Ford dealer in PX for a Focus ST. He really wanted to shift that car...! Keep an eye on the cost to change, not necessarily just the PX value.
