Thanks for answering guys
Like Rudy, the LS is also my choice. Lovely exterior design, admirable interior, great engine options and it has all of the luxury features you could want.
Following the LS my choice would be the IS. After that, the GS.
As for the rest..NO. The ES, SC and RX strike me as particulary ugly. The GX is ok, while the new LX looks rather overdone (particularly around the rear)
