Because they are just that..A concept..Also I'm sure the cost has a big impact on it:) How are ya Jag?

Concept cars are used to gage the public/media reception to design and ideas. This can go either one way or another...!
If the reception is good, then they may make as seen - although this will normally end up being altered in some ways and some parts of the designs being kept.
If the receptions are bad, then back to the drawing board.
Overall, its to gage public/media opinion and can help with positive PR work.

good answer!

Concept-is a noun meaning something thought or imagined-Imagine selling one-actually you would have to imagine selliong a million of them

um, cost?

concept cars are made to get feedback from the public and based on the feedback modifications are made if the response is positive or scraped if the response is negative.

I liked the camero concept car 2 years ago and I am wondering if it wll come out.

They are making it...will it look like the concept??

OK, now I am really confused! If they really don't make them, how do they make it look like they are really on those round podium display things at the car shows? WHOAAAA

Uh, why can't I buy one?
Sorry, no Toad discrimination here....
Actually whats on the turntable at the show is a hologram....
ever notice how only the model can act like she touches it???
sorry can't give away any more industry secrets....

Rather like Disneyland, wouldn't you say...that little 10-inch prima donna telling everyone goodbye. LOL

Because the average car buyer would not be able to buy them my friend.

Just the beautiful design of the sheetmetal...I dont need all of the gee whiz stuff.
thx Brian

I agree. I am a Porche man myself.
