It's an NHS salary sacrifice thingie with Knowles Fleet/VW Leasing. My wife spoke to someone at Knowles Fleet and they tried to say Tesla only deliver on a flatbed to your home (which I know isn't true from this forum!), but then conceded that we'll be dealing directly with Tesla for all delivery matters anyway. I've basically told both the sales rep at Bristol and the delivery team via email that we'll go anywhere, anytime, to pick it up as early as possible.
We'll just have to see what happens...
