Concept Spec V looks much sportier

Has anyone seen the concept pictures of the SE-R Spec V? In my opinion they looked much sportier and different than the regular sentras. It had a larger, rounder spoiler and bigger side extensions. The back bumper was lower as well. The rims were 5-spoke chrome wheels. Why would nissan remove those features??? Does anyone know if those extra features can be bought and installed???

Here is the link to the pictures:

No, because they don't exist.

If they don't exist to the general public, why would nissan even introduce them in the first place? What does Nissan do with their concept cars?

It's just to show us what the car is probably going to look like. The reason they redesigned it for production was probably a cost reason. Those chromies would've cost too much for their target market buyers to afford. They want to get the Spec-V out to as many people as possible. As for the concept, it probably went into an internal Nissan Museum like most other car manufacturers.

It would have been nice if Nissan offered those features as optional equipment. They are nice and I would really like to add them to my Spec V.
