Unfortunately it has all gone horribly wrong, it was sold to another buyer yesterday or this morning.
I told the dealer in Plymouth I'd buy it yesterday, but could not get down to pick it up (self employed so a day off work costs me more than delivery of a car) and would happily pay for delivery to my house. They would not sell it to me unless I picked it up, due to potential liability connected with Distance Selling Regulations, so I asked them to reconsider otherwise I may have to leave it.
I then went to another Snows group Lexus dealership in Hedge End, on my doorstep, yesterday afternoon and tried to buy it through that dealership, I waved my debit card at them but there were only salesmen present and they told me a manager at Hedge End would need to speak to a manager at Plymouth during normal working hours, although in principle they said it should be fine and agreed to speak with Plymouth this morning and arrange to have it shipped up.
I phoned the Plymouth dealership today and was told that it had now been sold to someone who was prepared to collect it.
So that's that. I am in the hire car until further notice. I could have put down a holding deposit but didn't want to until we had terms agreed, that I suppose is the risk you take.
To be honest, I'd rather have the GS460 but with only 15 or 20 ever registered I don't see one coming up in a hurry.
