7 years old for a car that is likely to need a new battery in future

The failure rate on Tesla batteries is <1%. The battery has a 150,000 mile or 8 year warranty and further extensions to the warranty can be purchased. You are aware that if you buy a 100,000 sports car it's likely to need significant engine repairs in the future...

I'd happily have a £100k S with low mileage that's likely to do many years before having a problem if it weren't for the swastika on the back.

A fool and their money are easily parted.
A brand new Tesla Model S costs less than that, so would you happily pay more for a 2nd hand car?

How do they define "failure"? Many devices with rechargeable batteries specifically exclude performance deterioration with use and consider a "failure" as in due to "defect in materials or workmanship". But some companies will include performance deterioration if you purchase the additional cover. eg Apple standard warranty only covers "defect in materials or workmanship" but purchase Apple Care+ and you get wear over time included except the cost of the additional cover is far more than the cost of replacing the battery.

Batteries that have very little range or failure to accept a charge.

All EV batteries degrade, mostly in the first year or two, then plateau around high 80% of new capacity and will stay there for many hundreds of thousands of miles.

Rarely do they fail to make the vehicle practically unusable

An EV isn't a mobile phone. The battery is vast in comparison. Tesla define failure as losing 30% or more of total capacity within the warranty period. In the event that the battery does have a major problem it can often be solved just by replacing faulty bricks in the battery.

Total battery failure is incredibly rare, and the models most affected are the oldest ones. 2018 is not old for a Tesla. Remember that the S debuted in 2013 so by 2018 a lot had improved in terms of the battery.
