Looking at the UK Lexus site, I think they've done that over here too.
To get my middle spec (SE-L Nav in Ultra Blue) now it would be £28,010 on the road. I think it was £500 less than that a few months ago. Curiously, cruise control is no longer listed as an option pack but as standard equipment so that would account for the +£500 here.
The other price options over here are :
SE-I (fabric seats) - £23,750
SE-L (leather seats) - £25,650
SE-L Premier - £30,950
The UK configurator seems a little messed up though because it isn't allowing options on the Premier (like radar cruise control and the lateral dampers) and isn't listing the F-Sport even though the F-Sport is featured on the web page. The finance calculator is also working off old data.
PS I'm not looking at the used info in case a price drop scares me !
PS2 Not that I'd actually care much, I've been enjoying my CT for the 2+abit months I've had it so far
