You could also find a free model, download that and use it as your blueprints. When done delete the downloaded model. I did that for this car pictured blew, which is a ZAZ 1102 which has almost no useful blueprints either, this was really useful for some of the curves of this car. The bendy door is from the jelly jbeam. I think that this looks good. EDIT: DO NOT SIMPLY TRACE THE MODEL.
