I heard this on the radio yesterday. I was told by my dealer that if any other offers came out bettween me ordering and taking delivery of my Mokka then I would be entitled to the better offer.
After looking through some of the small print this offer is very similar to the £500 free fuel big event weekend. "£500 given back to the customer on a prepaidpayment card for fuel (which im told doesnt have to be fuel).
Or £500 of the total price on ordering. (think it saves on sending out the card)
Mokkas are not included in the£1000 vauxhall deposit contributionin either case but are 0%APR for up to 5 years.
just so you can compare the ads have a look
