Fair points I guessI did! Back when the hatchback came out I went for test drive at same dealership and they were only asking for a £500 deposit at that time.
I was told they have had many incidences of people ordering cars and then changing their mind and not wanting the car which then left them having to try and sell it on the forecourt. This was why they now required a larger deposit so as to put people off doing this. Actually 6 months on I am seeing the funny side of it because having now experienced an unbearable wait for the car I suspect it was more likely a case of people getting fed up and giving up waiting
