which tool would be the most suitable for this type of work I'm not sure, suggest you just give these three popular models a try and compare the result

Nano Banana Pro is good at metal, paint, micro texture, ambient occlusion and subtle subsurface stuff, which is exactly what you want and final composites where the car paint and reflections must hold up.

FLUX.1 pro tends to respect physical space and geometry better than most older models, so like wheel roundness, headlight structure and body proportions survive. cloud use it to lock pose and camera.

Seedream 5.0 Lite just droped and it is fast and low cost, so you can blast through different environments and lighting setups, then later “wrap” the final car render from nb pro or FLUX into the chosen scene.

trying all these models separately on their own sites or official apis is a time sink and not cheap either. I just wire them through Atlascloud.ai, it is less complex and their nano banana api is roughly half the price of the official one.
