I just ignored the 3 year thing, given my 2003 Corolla has had about $500 worth of work in its whole life.

I wouldn't think I'd put in 3 phase power for faster charging, given I charge 25km per day. I might have to have my shed rewired as it's a bit old, not sure I'd want to put 10A constant through that wiring for 4-8 hours per night.

A lady I know just bought a Tesla S.

I did not ask her if she had done any calculations; I worked on the assumption that if she could afford the car, she wouldn't be much bothered...!

Going to be $2.25/l round there parts very soon. Thanks Jacinda!

As far as I understand there has been no changes to the tax on petrol after Jacinda was elected.

You might want to check the price of oil though.

Are you saying Jacinda is responsible for the world price of crude oil?!

I see there are plans to add a fuel tax in Auckland: But if you ask me, they should add toll roads and rush time fees in Auckland to deal with the congestion problem.

10 year old corolla. 210000km. Just replaced rear brake pads. Not sure if they have been done before. Still original clutch. I’m confident I’ll get to 300000km in it. So hardly falling apart. Oh replaces the original battery in it when it was 8 years old.

go corolla

Same could be said for any high price car. Hard to talk about return on investment on any car in private use. But the cost/benefit calculation for any luxury car is even worse.

Doesn't mean I don't want a Tesla Model-X, Jaguar I-Pace or something similar, but if I were to buy it it wouldn't be to save money. :D

Edit: That said, comparing a Leaf to a similar sized ICE and comparing sticker price would not help you much either. You have to look at cost of ownership (services etc), as well as cost of fuel. You can afford to use more for a Leaf than an ICE if the day by day costs will be sufficiently lower than the ICE to offset the price difference.

Are you wanting to factor in putting in 3 phase power, if you want to charge it faster?

Currently 3 phase power is more important in the USA than in NZ. As a normal USA power socket is only rated to 1.4KW continuous load. While normal NZ sockets are rated to 2.4KW continuous load. And it is usually not to hard to get a caravan socket added in NZ which is rated to 3.6KW continuous load. And the Nissan leaf doesn't even support 3 phase charging anyway.

I intend to add 3 phase charging capability to my house. Although knowing me, I would probably have 3 phase charging capability installed before even owning an EV.

Aredwood: ... normal NZ sockets are rated to 2.4KW continuous load.

Right... so even with an ordinary single-phase outlet, a 24kWh battery could be fully charged from dead flat in 10 hours, plus (say) 5% for inefficiency in the charger.

The tool seems to favour petrol cars (Mazda 3) because it rates cost of sevicing for 3 years at $0

As it happens, that's exactly what I have paid for servicing during the first three years ownership of my Mazda3.

go corolla

1999 Corolla GL, 310,000km, two clutches, two cambelts. When anything breaks, I can glue it back together. If I hadn't into stuff it would be in pretty amazing condition.

Contrast that to my 2007 Mini Cooper which has eaten about 3K worth of parts and labour since it came off the boat in May last year.

Similar with my 1997 Primera. I got through two clutches in ~300,00 but it was used extensively as a tow vehicle. No cambelt. I replaced all the shocks and the brake rotors around 200,000. Sold to a friend of a friend and I understand it's still behaving itself.

I don't mind stuff going wrong, it's an 11 year old car. It's the extortionate pricing that gets my goat.

As a result I am now seriously considering hanging onto the Corolla and swapping the Mini for an EV.

cant buy a leaf new in nz so not a very good car for a comparison.

Will / Should be available next year

So I think it’s worth considering.

This is seemingly a pretty common feature of recentish Japanese cars - our Mazda 6 is just short of 300,000 and still trucking along with modest servicing costs each year

You need to be doing higher daily km's to recover your costs. At 25km per day, you will certainly save on fuel, but your fuel bill won't currently be high so what you save won't be as much as what you loose in depreciation compared to an already paid for ICE.

If your ICE has just been retired/totalled/stolen and you want a ~$15k-$20K car anyway, an EV could be a good replacement vehicle.

At this stage of the game selling a perfectly good ICE and buying EV would be more of a Geek factor or a environmental choice than a cost saving measure.

You don't need 3 phase power in NZ. To begin with Leaf's are single phase. Even if you get a bigger flasher (more expensive) EV with 3 phase as an option, you still don't need 3 phase. An EV will get about 7 km per KW/h, so your commute of 25km will consume approx. 3.6 kw/h. It would take an EV on a regular 10amp outlet (2.4kw) 1.4 hours to recharge from that - so no, you don't need 3 phase.

The 3 phase myth comes from the USA where they have a lower voltage (and inferior) power supply, and does not apply in NZ. In the USA they have 3 phase in the houses because 115 volts just isn't enough for grunty appliances (driers, stoves, EV's) and they want/need 200volts so as to cut down of the thickness of the copper wiring needed. Although it is 3 phase feed, they only use two conductors, wired phase to phase to get single phase 200volts, approximating our regular single phase 230v domestic system.

Edit: Spelling.
