The reason I'm asking is because I'm going to buy one soon and I have two options. One is a p85d with a brand new battery at a dealer and the other one is a p85dl on the original battery from a private seller and I also have a trade-in that's worth a lot so I would have to sell my car and hope the private seller doesn't sell the car and I end up with no car. Both around the same price. I rode in a p85dl with ludicrous and the acceleration was incredible and exactly what I want. I really only care about the first 3 seconds of acceleration that hits you like a brick. Is there a noticeable difference between the two in acceleration in the first 3 seconds at a launch or is it not noticeable? I really think the one with the new battery pack is the better option because I can upgrade to ludicrous later on because I read tesla is accepting preorders for it again and my main concern about buying a used tesla is the battery pack. I just worry they'll discontinue it like they did before because Tesla does weird things like that if I'm not happy with the acceleration of the p85d.
