Oh I wouldn't walk away because of the smell....after all, all it takes to get rid of it is to remove the source, remove the complete interior,while you are there you might as well fix the floors and oh that wiring doesn't look so good better rewire the car, then you can paint your floors, before you steam clean and reinstall the interior you might just as well do whatever bodywork is neccessary then at least shoot a coat of epoxy primer on it. All those welding, bodywork and paint smells will have your pride and joy smelling like a new car in no time.......see easy:)
