Small problem which his local mechanic could not fix, you need special training now to work on them.

Went back to see his mate who managed somehow to get him one for only #$7500.
Obviously one of the major problems with electric vehicle swill be ongoing problems with batteries.
Conventional cars will go for maybe 250,000 miles on the one engine, batteries currently only good for around 55,000 miles before a new one is required.
The main problem is the efficiency of them, rechargeable batteries on each recharge lose some efficiency to hold the full charge.
Once down to around 60% in USA they have to be replaced, the ones taken out sold on to households to go with solar panels for back up.
But once down to 40% not worth keeping.
The electric car has about ten times the copper of a conventional one, problem now is that many of the current Copper mines are coming to the e nd of their useful life.
New ones need to be found, which is proving to be harder than first thought.
To add to the dilemma one minarologist said that by the hear 3000 the world will have used all the available natural resources such as Copper, iron, oil etc.
But he added that there will still be one that man will revert to for heating and cooking, coal.
