Sorry for the zombie bump, but I've been looking at a used S60 that has almost the exact same stats -- 2014 that shows about 160 miles at 100% charge after ~70k miles. Owner told me he took it to SC who said there's nothing abnormal...so it doesn't sound like they're keen on replacing the battery. Wondering if the OP in this thread or anybody else has thoughts.
My quick Googling shows this seems far below average for a car with that mileage, so I'm obviously concerned. The price reflects the range (and a couple cosmetic things), so it would be a pretty great deal. That said, the battery is obviously the most critical and expensive part of the car so I'm trying to get as much info as possible. I've also have Tesla do a pre-purchase inspection were I to buy it, but sounds like they're not likely to admit any fault on that issue.
