@Talock2018 Keeping in mind that the 25% SOC driving range test is an estimate, that 2013 SL is likely going to lose it's first capacity bar soon. The useable capacity on a brand new pack is supposedly 21.3 kWh, so 18.3/21/3 = 86%
So, for a 2013, the pack seems to be in good condition as most 2013s have dropped the first capacity already. For an SL in that condition, I think $9000 would be a target price to pay for it.
If the 2014 SV likewise has a healthy pack for its age, then it's likely got a 4%-6% higher SOH than the 2013 SL. However, the manufacturing date on the 2014 SV could be only a few months younger than May 2013, since some would have been built in late 2013.
So, you might get an extra year of "useful" range from the 2014 SV. Wild guess though, as the 2014 SV could just as easily have an SOH of 85% or 86% too. Personally, I wouldn't pay more than $10000 for a 2014 SV with a good battery pack as very little changed between model years.
Getting Leaf Spy data on the 2014 SV will help you make the best decision.
