Just FYI, I've seen that site quoted a few times, here at is300.net, they apparently must be Canadian. As I've seen some confusion over the prices they quote.
They say base for the IS is 40k when it would never hit 40's... and he said out the door was 46k, I think that would translate to about right if those were Canadian $'s.
Also if any of you remember there was an article about the Mercedes Benz S430. They quoted a 100k+ price there too... make sense now? S430's ought to be around high 60's to 70k's and S500's around 80k. So 100k Canadian sounds right.
I guess just sort of as a heads up, since I've observed that ppl like to quote this site quite a bit.
