... They can't offer two prices depending on how you pay. You are perfectly entitled to negotiate a low price for cash then turn around and say actually I'll take the interest free deal at that price.
Of course they can. If you are negotiating on the basis of cash, then you aren’t negotiating on the basis of interest-free (a.k.a. 0% interest). You can try and take the cash price on 0% interest you are changing the basis for negotiation. Good luck, it might work or it might not.
If the car yard offers a lower price for cash than "interest free" finance they are breaching the fair trading act - if there is a lower price for cash then finance isn't interest free, it has a hidden interest rate. There were some commerce commission prosecution of the usual appliance store suspects many years ago because of this practice.
