Well it's based off of the Barstow, but it's not completely a Barstow (or American for the matter) It's based off of this.
I'm also a fan of skylines, (from all generations), but the car I'm making is based of the C110, also known as the *2nd* generation Ibishu Miramar (hint hint )
Also I should start 3d modeling again. I want to make a coupe version of a car or something A face lift maybe What car does not have a coupe version? the new pessima?
