low-poly car 3d model

Create a 3D model of a low-poly style chassis shell inspired by a classic Fiat Uno for an Arduino RC car. This model should represent only the top bodywork of the vehicle, capturing the iconic boxy and angular design of the Fiat Uno. Focus entirely on the upper body, with no windows or windshield, keeping a solid, stylized shape. Include dedicated square-shaped wheel well cutouts with noticeable clearance to accommodate rubber RC car wheels. The design must have flat bottom edges optimized for 3D printing. Output a clean, watertight mesh suitable for STL export, containing just the top outer shell with a low polygon count between 1500 and 3000 polygons, with no wheels or internal electronics.
