I'm looking at buying a used MS and have a few questions, first I'll give a bit of background. I'm a Software Engineer in the Bay Area as such I make a decent income. (heyoo from san mateo) Generally I buy off lease luxury cars, previously I had a G35 Coupe and currently I'm driving a Lexus IS250. I had been planning on getting a Model 3 when then came out but baby #2 is on the way and my wife threw in a wretch that the next vehicle must be 7 passenger (To accommodate carseats + mother in law) . I checked the options and had resigned to the fact that I would likely be buying a MDX or Lexus GX until I noticed that used MS were down to the low 50s for 2013 MSs that are relatively low mile (15 - 30k) which seems pretty reasonable. (Woohoo 7 passenger requirement met, throw the mother in law in the back) Timeline for purchase is about a year I'll likely start looking at the end of 2016. I would like to find a car in the 40-45k range and I'm hoping they'll come down to that price range by the time I'm ready to purchase. So onto the questions: 1) 60kwh has enough range for my current driving habits (around 150mi/wk) is it possible to upgrade to a larger pack at some point in the future (even if it requires some, ahem software ingenuity) or is there some hardware limitation other then the battery in the 60kwh model? 2) I know the 2.0s came out in 2014 and the next refresh is here. Are there any major deal breakers in a 60kwh or 85kwh single drive from 2013ish? For example early Porsche Caymans (2006) had a nasty habit of becoming oil starved and ruining the motor. 3) Are the drive unit failures still a large issue even if they have been replaced? 4) Any special financing issues (or benefits) that you would not find on a normal ICE car? I would be putting 10-15k down. 5) Anything else I should know? 6) Looking for a White w black/tan interior with the rear facing seats, lowish miles and in the $4x range sell me your baby.
