Given than even direct line dont have the MY listed I'm not at all surprised Sheilas Wheels didnt either, but the CS person I was talking said she'd gone and "asked" and it was still no. But I suspect the supervisor may have just been saying "if the computer says no...."Is that currently or forever? I'm with them too and Model Y isn't listed yet when I try to change the car online. When I spoke to them last week they said its not listed yet and its best I call them closer to the delivery date.
They do give you a daily pro-rata refund so I'll wait until the day after collection (just in case, COVID and all) and then cancel if they still aren't offering it.
The cheapest quote of £422 was with Bell (owned by Admiral) but you have to install a box for 6 months.
On a related note.. windscreen cover will be essential but worth noting I had to wait 2 weeks to get an Outlander rear screen via Autoglass. The Tesla rep at Thorpe Park admitted spare parts for MY's will be tight until the summer so god help anyone who gets a crack in that lovely supersize front windscreen
