Providing you receive confirmation from Landrover that the settlement has been made i would think it should be fine and that funds are fully cleared within your account. I do think funds can be withdrawn on the same day of the transfer from the sender, so maybe move them to a seperate account as soon as they go into your account.
When i look at an ED30 with VW finance on it, i rung VW and they explained that once the payment had been made they could email me a confirmation on the day, but it would still show on any HPI check for a couple of weeks.
