Well I found this car in some forums well its a graphics i know
But this car looks like babe of my dream .
The author said its a sbx-300 but he dint mention a manufacturer name

I've never seen that before, and I've never heard of an SBX, so I guess I can't help . I think that car may be made up. Notice the "Pedram" sticker on the side that appears to be the last name of the person who made the picture. I think it's a computer model of an imaginary supercar.
Nearest I can tell, the only real SBX-300 is a Japanese wafflemaker:

I think it might be concept art, all I can tell you is that its an MR setup 
I think the easiest way to find out the truth would be to e-mail the address is on the lower right corner of the picture.
If it is a real car, then it looks like it is much modified, but I don't think it is. Where's the background? Why is the shadow such a smooth gradient? Why is nothing reflected in the rims or windows?
Either this is the product of an extremely well made photography set up, or it is computer generated.
Notice the "dream car" in the link. This is defiantly a vector image. I have to say it is very well drawn, must have taken a few hours. Well done Alexandre Pedram!
It looks to me like it was rendered in 3D using a 3D modelling/rendering program of some kind. Maybe a college design project.
Definitely looks like a concept or drawing. If you wanted a similar-looking real car, the first thing that popped into my mind was the late Toyota Celica, even though they're obviously not the same car.
I don't know 
It's a render of concept car but it may be visualisation of new tuning-look of Toyota Celica. Car shapes looks very similar... Compare to this: http://www.damox.com/cars/thumbs/Toyota/Toyota_Celica_Veilside.jpg
sorry!.
I don't know....
Lol... yeah the first thing that came to mind was the toyota celica :X
And yeah, it is a MR lol -_-;
The car does look bad ass though.. perhaps it is a concept car?
After seeing the link -
I just want to say - its just a designed car not specificall y owned by any company or any car king (just kidding)
So, It is just a lol
