That’s only £4K discount, I managed to get just over £7,850 discount from Nissan Worthing. £5,000 Nissan finance contribution and £2,850 ish dealer discount.
I think the £5000 finance contribution had been reduced to £4K however you should still be able to achieve around £6,800 discount plus also save around £400ish on the finance deal which I had as they have reduced the interest from 4.6% to 3.49%. Also 2 free years servicing deal on offer
Give James Barron at Nissan Worthing a call
Hope that helps
