I was talking to someone with a Nissan Leaf a little while ago and they were saying that an electric car has far less servicing costs than a petrol one. No oil changes, no filter changes, no exhaust to rot... I hadn't really thought of this until they said it.
Quite probably the tyres last longer too - well, longer than us performance dino burners here get through them anyway... plus they are all skinny tyres not low profile wide ones like we use.
It *might* offset the increased price over say 5 years you know... assuming the battery replacement thing doesn't happen and the depreciation.... oh I don't know!
Sounds like a finance question for MonkeyHanger
