For car finance, I think that ptsb will offer 6.9%.
There is also a crowd called Finance Direct that are offering what appears to be fairly competitive rates through the Internet Car Company. See [broken link removed] for details. I can't actually find any reference to IFSRA anywhere on the site, so I'm not sure in what guise they are able to offer finance. Looking again, I see that the options available are hire purchase, lease purchase and leasing, so maybe they are regulated by the DCA rather than IFSRA?
