It really depends on where you are. In Bellevue Washington on a trip I saw three in my hotel parking lot alone. In central and southern Oregon I have never seen another one while driving mine.

 

I see IS's all the time now-a-days but dont think Ive seen another IS350 yet.

 

So, can we conclude the IS350 is an overall low volume (not exclusive) production car because of its price? Lack of interest from the world market? Or just low production due to Lexus' pov in keeping it somewhat low?

 

It all comes down to warm weather states have the 350's and cold climates have the 250 AWD's.I would only buy a FWD,4WD or AWD in my area.
I don't think I've seen one 250 RWD in my area.
More rare than a 350.

 

I love my 350, step on the gas and your gone
