This model is mostly based on electric automobile from 1910, produced by Baker Motor Vehicle Company. It is not a perfect copy, though.
It is made of two PBR materials. One has 8k opaque textures, and second is 4k transparent glass texture. It is realtime friendly (you might want to downside textures to 4k and 2k) and can be also subdivided- it has supporting loops to maintain shape.
In addition, I uploaded .blend file with textures inside.
Interior is pretty basic. I focused more on complex mechanism underneath.
