there's a 2014 2LT with fast charging option and about 50K miles in great condition. seller says charging cuts-off/stops when it reaches 85 mile range. i can get it for $6800, or pay a few thousand more for a 2015/16 with about half the mileage, all other things being equal... what would you do?
Ive heard good things about the 2014 and with a good battery you might be in good shape for that price, and just a matter of personal preference if the interior and suspension are good. I wanted a very low mileage and newest year car because my used car experience has been mixed. The spark seemed like the absolite best deal for both age and miles out there on any car, not just electric.

....right after an afternoon full charge (which I rarely did).
But what about allowing the BMS to do its house keeping? I believe that takes place after the 'full charge'.
BMS 'balances' the cell voltages.

But now that I say that,,, how does a Bolt or Leaf or Tesla handle BMS duties when the charge is limited to 80% SOC or the 'Hilltop' setting on the Bolt?
1) I would (purposefully) fill the car up to "full" about once every 6-8 weeks (and leave it plugged in for at least an hour afterwards) so that the car could "top balance" the batteries. I figured that was often enough (since in 2 years I only went under 10 miles range ONCE). To me, that means 'rarely'. (I have already done by 'full charge' for the months of Jan and Feb ...)

2) The Bolt, when using the 'Hilltop' setting, balances at 'full' (which just happens to be at/around 88-89% of full-full :D ). Basically, 'full' means "when the battery hits a certain voltage that we programmed into the vehicle". When on hilltop, the voltage is simply lower - it still balances the voltage across all cells, just at a lower voltage point. It would probably be a good idea to fill to 'full' 2-4 times a year, but ... Remember that even at 'full', the cells aren't being filled to their theoretical/design max - a 'buffer' is reserved at the top to help with battery longevity. With 'hilltop', that buffer is simply larger.

Note: the full-charge GOM mileage value is very dependent on how the car has been driven and driving conditions. I see GOM values of 95 to 100 miles in late spring through early fall. In winter, I use the heater and my full-charge GOM valued drop to around 70 miles.
Yeah, I was rather suspicious when the used Spark I recently bought had *exactly* the EPA range of 82 miles at the dealer (I think that it is possible to 'reset' to factory, and was worried that the seller had done exactly that to hide a bad main battery). I checked with Torque and the battery was in pretty good shape, and since I have mostly been driving it around town (very little freeway), the 'guestimate' range shown on the console is slowly creeping upwards. The max I ever saw in my 2016 was 115 miles on a beautiful June day, about 74 degrees, right after an afternoon full charge (which I rarely did).
I have seen the same thing. Now I just estimate my range by using a value of 5 mi/kWh and multiply it times the battery capacity as measured using TorquePro. In the summer I see 6 - 6.5 mi/kWh - sometimes higher depending on how much I use the AC. In the winter I see 4-5 mi/kWh - sometimes lower - depending on how cold it is and how much I use the heater. This morning, after a cold morning start and using the heater, and a short 4-mile trip, I was at 4 mi/kWh in my 2014 Spark EV. My current measured battery capacity is 16.5 kWh which, at 4 mi/kWh, results in an estimated range of 66 miles. Now, I pay the most attention to my TorquePro measured battery capacity and the rate of degradation.

If you really want to have some fun, get on the freeway and draft a "big rig" for 10 miles or more. I have seen my miles / kWh go as high as 10! This does wonders for the GOM range! :lol:

thank you for your help Gentlemen, i am now a proud owner of a silver 2016 Spark EV 2LT with 46K miles and fast charge option bought today, 3/14/19, from MK Smith Chevrolet in Chino (SoCal) for $8500 OTD, slow - 120V charging in the garage right now. the car was originally leased from this dealer in August of 2018 by the first and only owner, which makes it about 2.5 years old. i was going for a fresher battery vs. low mileage and i think i found a good deal. also, i considered the GM warranty on main battery of 8yrs/100K miles and it's half way there so... please let me know your thoughts on my purchase. thank you

two things i didn't expect, i has no backup camera and came with just one key fob... other than that, I'M IN LOVE :)

Those dogs. You should have held the line for 2 key Fobs before buying it. Oh well, too late now. They won't do the right thing, I'm sure.

Do you know about selecting 12A L1 charging at each shut down? The default is 8A.

I have a Garmin DriveAssist with a built-in Dashcam and the optional Back up camera. The backup camera only needs a reverse lamp input and a ground. It comes on really fast! I have the 15 DCFC stations in my metro area saved to it.
It's also fun to watch distance to destination vs. GOM when cutting it close.
On one long cold airport run I had to turn down the heat and slow down and watch those numbers trend in my favor!
Used '14 2LT w/ DCFC.
+65k miles. Only one LONG visit to the shop....

thanks, i know about 12/8amp option. i asked for the 2nd key fob but the sales lady said it came with just one. i thought that 2LT optioned models came with a backup camera, oh well. kind of hard to get used to not having one after driving with one for so long. i charged it overnight with 120V, unplugged the cord at the car without unlocking it first and the alarm sounded. that must be the anti-theft feature. have to remember to unlock it before unplugging. one thing to note, the 120V chord was never used on this vehicle as it was still tightly wrapped, factory rubber-banded and untouched. the previous owner must have only fast charged it, hence the higher mileage. i don't think it's necessarily a good thing for the battery.

my concern with the higher mileage was the suspension and overall feel of the car but this one feels solid and drives like it was on rails. i also checked the rubber CV boots on the front and they were in great condition as well. overall it's in excellent shape and must have been mostly highway driven to get to such high mileage in just two and a half years. time will tell...
