I've just found on Trade Me Motors the lowest price second-hand BMW i3 that I've seen so far.
It's a 2014 Gen 1 "pure electric" model with 17,000 km on the clock and it has DC fast charge and NZ GPS and aux etc.
The asking price is $30,000, so that's getting a bit more reasonable.
The advertisement says you can fast charge this vehicle to 85% in just 20 minutes, do you think that's possible?
Although the 2014 model has a maximum range when new of 130 km, I guess you would have to reduce this a bit for a 3-year old vehicle due to normal degradation of the battery over that time. So, do you think you could count on getting a range of 110 - 120 km?
Make sure the DC fast charging interface isn't CCS Type 1 (American standard)
I think there may be only 2 of those left in the country....and both of them will soon disappear. The fast chargers have all been converted to CCS Type 2 (European and - as of December 2016 - the NZ standard).
That particular car is an import from japan. You can tell as AC (everyday) charge port is in the frunk.
All i3's from japan that I have seen have a CHAdeMO fast charge port on the side, and a J1772 (type1) slow charge port in the front.
Cars from the UK have a type 2 AC port on the side (with CCS DC fast charge pins as an option).
Early cars in NZ had type 1 connectors on the side, with optional CCS pins (all had range extenders). I think BMW NZ has now swapped to CCS type 2, and were going to swap the plugs on the few type 1 cars. I'm not sure if they are still around.
Most early i3's in NZ and the UK didn't have the rapid charge option. Back in 2014 there were few fast chargers around, making it hard to justify the extra cost (especially if you have a range extender)
85% in 20 mins? - the 22kWh i3 has something like 18.6kWh usable capacity. To charge to 85% in 20mins, average charge rate would need to be 47.43kW. Given the chargers are rated at 50kW, it sounds close.
Regarding battery life on the i3, it's pack is directly cooled by air conditioning refrigerant. Most of the issues with batteries dieing on other EV's is due to inadequate battery cooling. BMW's solution is the best on the market. You can dig into the service menu and check the kappa max value as a proxy for battery health, but there is some dispute online as to how helpful this actually is. Main issues on the i3 are to do with the reliability of the REX (partially early models).
