Great information in this thread. I pick up my M3LR in about a week so have been shopping for insurance. I'm moving from a company car to purchasing the Tesla privately(due to switching jobs) so have been working through which insurers will give me credit for having no claims on my company car... so far Admiral has been the cheapest by doing a multicar deal at about £1100 for both cars - which is the same price I've been quoted for just the Tesla so it's about a good as I think I'm going to get.
I know also some insurers will accept company car history but I haven't gone down that route yet as I'm still getting a letter from my employers insurance company to confirm my driving history.
But I was curious to see how much the '0 years NCD' was impacting the price and so I added '5 years NCD' to see the difference and the quote went UP by £200 to over £1300; set the NCD back to 0 and it went down again. Can't understand the logic.
