Ok IS250 w/nav or IS350 sport with no nav? There both the same price up here in canada at$55700. I know if I got the 350 I could probably put in a aftermarket screen with nav but if I got the 250 I couldnt put in a new engine to get 102 more horse. Hmmmmm?

 

I think you answered your own question. Plus, who really needs NAV...those 102 horses will be ALOT of fun ;-)

 

I'd go for the IS350. HP > NAV

 

I'd go for the 350 and use mapblast to find my way around

 

I had the same decision to make as well...i was going for the g35 w/everything, 350, or 250 w/nav

Did you play with the nav? it wasn't nearly as slick as i thought it would be. the voice control was slow in my opinion, and give the technology another year or two and they'll have it down pat.

The best thing about not getting nav, is that you might actually be able to find the 350 on the lot, be able to actually negotiate a deal, and save yourself months of waiting! not sure about the 350 with a sports package though...you might still have to order that one.
