Just wondering out loud here.
If you chose to collect from a larger/easier collection location e.g. Heathrow rather than a smaller/further away location e.g. Stockport, are you more likely to get a car sooner?
My logic tells me no, but from reading up on these forums for a while, I've noticed that with Tesla, anything is possible.
My closest collection points would be Brum or MK but I'd be happy to head to Heathrow if it means I'm likely to get a car earlier.
