Illustrated Tee Vector Conversion

I have an illustrative t-shirt graphic that has to be redrawn as a crisp, print-ready vector. The artwork will go on press, so I need smooth lines, clean shapes and spot colors that hold up at any size. Please keep the multi-color palette exactly as in the original art and organize each color on its own layer to simplify screen separations later.

FOR REFERENCE:
This design was created using ChatGPT and it was unable to deliver the file type I set forth at the beginning of the project. I have each individual vehicle file downloaded from GPT and can provide those if that will make the project smoother. These vehicles were made using photographs of cars that were at last years event and need them to be represented accurately. Additionally, the image/design that has all of the pin striping was created using the vehicle images; however, their details and dimensions became modified when the addition of pin-striping and text were added. I wish to have the initial cars be more accurately represented using the full design details.

Deliverables:
• Fully editable AI file (latest Illustrator version) with layers clearly named
• Colors preserved one layer per spot color
• All paths properly closed and free of stray points

Once you’ve finished, I’ll do a quick zoom-in check on edges, run a separation test, and confirm everything scales to 100 × 100 cm without pixelation. If that passes, we’re good to go.
