3d modell ferrari testarossa 1:24

I need a 3D model of a Ferrari Testarossa in 1:24 scale. It should have the most important details, but should also be very minimalistic. No mirrors, and the quality must be very stable, because I want to do a casting mould with the car. I would like to have the project as an STL-File. I would need the 3D model completed as soon as possible. In the attachment are two pictures of a Porsche 911 as an inspiration for the project.
