Sorry if there's already a thread on this. A couple of days ago someone from Tesla called me about my order of 70D, and told me they can upgrade it to 75D for free. Definitely glad to take this $3000 saving I was also told that original delivery date targeted Sept but if I purchase air suspension ($1250), delivery date would target July. Accepted. I am wondering if all other 70D are upgraded to 75D for free or just a few people got luck? I ordered basic 70D early Feb, with only upgrades being 3rd row and blue exterior color.
