Hey guys, Long time stalker first time poster in a while on these forums. So I've been having a look at getting a Tesla, my friend is selling two (he owns a car leasing company) one is a P85D 2014 pre-facelift and the other is a Model X 60KWH. Now, this is kind'a a two part question: 1. I am looking at either the P85D or the new 70D with FSD upgrade for when it comes out... what is the difference between the pre-facelift and facelift models? Does the pre-facelift only come with AP HW1 or are there pre-facelifts with AP HW2? What are the other differences? 2. Do all Model X's even the 60Kwh ones come with the option of a software upgrade for the battery? Do they have AP HW2? He's selling this Model X for £61k which to me sounds like a steal. Low mileage too. Anyway, your thoughts would be highly appreciated. looking forward to becoming a Tesla owner!!
