I'm picking up my Lexus IS200 next week, I can't wait!
She's a 2 year old SE with a big spoiler on the back (higher than the lip spoiler on the Sport). I'm also having Sport scuffplates fitted this week... the dealer threw them in as a sweetener which is nice.
When I first saw the car I assumed the spoiler wasn't a Lexus part but the dealer assured me it's a genuine Lexus accessory and an available option - it's just that I'd never seen one before (and I've not been able to find anything about it on the web yet).
As soon as I get the car I'll send in some pics - she looks a beaut!
