I'm a little lost on the break down of the abbreviations. What are the differences in the P3D+ and the P3D-? It's my assumption that the P3D is a Model 3 Performance with dual motor. I ordered 8/31 and the performance only had the option for the larger wheels brakes etc.. If you ordered a Model 3 Performance the only things you could change were the paint color, interior (white or black) and full self drive or not. What's the extra $1k +option? I ordered 8/31 model 3 performance white/ white with full self driving. I'm in AZ and no information as of yet from tesla.
