Finance a £40k car

[gingerbeard]

Hi all, I hope I am posting in the right place but please feel free to move it if not.

I have been offered an outstanding deal on a MK1 Sierra cosworth for £40k when they are about £70k currently.

What is the best way to finance this please as it is my dream car and I do not want to miss this opportunity.

Many thanks in advance for all of your help

Chris
