Do a search on insurance, as many of us who got their cars 12 months ago had the same issue - go direct to the main insurers, e.g. Aviva, LV, Admiral, et al., they can usually normally add it over the phone, LV did in my case this time last year - a comparison site is also useful as it will give you an indicator as to who will offer insurance on the ER, also dont put in the reg, but search manually. If the worse comes to worse, just put in an equilivent model that exists and then sort it out via phone afterwards. From recollection I think i had to do that?
