BMW i3, Tesla Model 3 or Cayenne e-Hybrid

[ImABitLongCars]

Hi guys

Returning to the UK to central London after years away and pumped to buy a car.

Budget is £8-18k and options are:
- BMW i3, kinda model agnostic for the right spec
- Tesla model 3
- Cayenne e-Hybrid (post 2015 facelift)

All are cheapish to run save for the insurance, servicing and depreciation on the porsche.

Speed and handling are irrelevant, needs to be cool and be a good enough family runabout for London and the odd kind journey.

Waddaya think? Any owners experience or running these?

Any thoughts on what model 3 is the best to go for?

Thanks!
