This "deal" is looking less and less likely by the minute. Thanks. This has been really helpful.
Don't overthink it. How many miles do you expect to drive in a day? (Is the car a REx?)
I have a 2015 REx. Bought it with 10K on the clock, and it now has 22K. Most of my 'day' driving I rarely log more than 15 - 20 miles. I have occasional days that I hit 30 maybe 40 miles. I've had only two times in 2 years that when running multiple errands, I had the REx come on, and both those, I deliberately kept running around just to see the REx come on. After several days of very short 5 - 10 mile trips, depending on outside temp. my range after charging that night might be 55 - 60 miles. If I take a longer drive of 30 - 40 miles, and charge it up, next day my range is 75 miles (and the car is rated at 71 miles max range in the literature). Oh, and I always drive in Comfort mode - never use Eco mode. If after several years of ownership, even if my range drops to 50 miles max, I'd still be using the car exactly as I do now - do my daily drive, plug it in at night to charge as needed. Seems like the price you are getting is good, and if the battery is currently showing decent range, and you don't have a high mile commute that is pushing the limit of the car, if it was me, I'd not be worrying about a 'what if' that will have almost zero impact even if that unicorn event of a degraded battery pack actually happens. After a longish trip to and from my daughter's house (40+miles) for Thanksgiving, plugged it in overnight, and when I backed out of the garage, it showed my range at 80 miles. Of course that dropped immediately to around 70, but still - 70 miles is about what the car was rated at brand new. With the car fully charged, and using 'conditioning' during the charge - what is the range showing?? On the BMW i3 board there are lots of owners with over 100K miles on their 2014 and 2015 i3's with little appreciable drop in HV battery performance, some even over 200K.
