Found the model online, cleaned it up and created an STL of it. No support needed, completely hollow. I printed mine with a .3mm layer height, I will try it again with a smaller layer height once I finish setting up my printer with a smaller nozzle. I suggest a using a fan. The wheels are in a separate STL I just drilled holes in them and mounted them with nails, My plan was to model the axles but I got distracted. Because It was imported the model isn't perfect so don't be too surprised if your g-code crater complains about it a little. The side mirrors have a removable support.
