Hi there, 
I am waiting for you to see the details so that the transaction will get started. I can assure you that if you still have doubts they will all go away after WorldPay will contact you, with the details of the downpayment, and my member status. Please send me the details so that I register you at WorldPay. You will e contacted by them and if you will not agree, then there is absolutely no problem. Please contact me ASAP with your full name, shipping address (for shipping) and a telephone number so that the WorldPay agent will be able to call you 24 hours before the car will get to you. Thanks!
