Well to update this thread, I decided to go for an I3 /I3S depending on what was available.
Not wanting to wait 3 months for a factory order from my local dealership I phoned the next few places to try and find something ready built.
Sytner in Cardiff managed to find me a ready built S model without any options which is what I was after, albeit my request for a discount on the AP was politely declined.
Unsure exactly where he’s sourcing it from but it’ll be at the dealer in 10 days or so.
It’s in white with black bonnet and roof.
