I'm considering "upgrading" to an early P85D. Q1: Can a second owner buy into the Ludicrous retrofit upgrade? (see: Tesla — LUDICROUS MODE ONLY (P85D) - PRE ORDER DEPOSIT) or is only the original owner eligible? Q2: How hard would it be, and how long would it take, to do an entire "decor swap" between two cars? (one car is Carbon Fiber, the other Piano Black, I want to swap them out). Q3: I had a third question, but I can't think of it right now.
