Used BMW i3 (2015)?

[OnlyYou]

I found a used BMW i3 that is the 2015 model for under £15k. It is going to be 8 years old at this point which is one of my concerns because I don't know the health of the battery. Does a price like this mean the battery is not likely to last much longer?

I do like the colour of it. It comes in this one but obviously not as new/clean:

It is worth looking into the mileage and if this car is under warranty for a battery replacement. It may have already had a replacement as well. If you are going with a dealership, ask them what the capacity and health is at for the battery. They should be able to give you a percentage or tell you the current kWh of the car.
