Here is what I don't get. Nissan is the parent company of Infiniti. Why wouldn't some designs be similar? So there is some similiarity between the side profile of the new Altima and the coupe concept...shouldn't there be? They are produced, essentially, by the same company so shouldn't there be similar design cues? How weird would it be if the altima looked absolutely nothing like the G35, and vice versa? If it didn't, then we would be complaning that the new Altima coupe doesn't look like a Nissan product. I confuse VW's and Audi's sometimes. Not too much anymore because of Audi's huge shield-like grill.

I think that similar design is correct and should be expected. At the same time, once both the Altima coupe and the new '08 Coupe are on the road, I'm sure you'll be able to see the difference.
