I have always wanted a 3D printable Oscar Meyer Weinermobile but I don't have the skills or software to do this. So I cheated...
I found out about the Tripo AI generator website (https://studio.tripo3d.ai/home) and gave it a shot. It can generate an STL file to download from a photograph. The resulting STL file that was generated really surprised me; it even has a detailed undercarriage! I printed it and was very pleased but the rear view mirrors are very fragile and broke off because of the small attach points. I used Meshmixer to beef up these areas and hopefully didn't make it look too far out of proportion. I also cleaned up some surface areas (the side door was mirrored onto the other side). This model requires supports; I used tree supports but had to add custom supports to the lower surfaces of the mirrors and mounts as they were not generated in my slicer. Also, as the entire undercarriage will require support. Be sure the top Z distance of the support is worked out in advance or else you may not be able to remove the supports. On my printer, 0.3mm distance works perfectly.
