I'd recommend Hibernian or Allianz - if you are still a named driver on yr wifes vehicle, they SHOULD allow you 2/3 yrs NCB for being a named driver for so long. If not, the best way is probably a cheap car, TPF&T with Quinn direct and switch after 12 months. Hope this helps.
Quinn Direct give almost the same discount for named driving experience as they do for NCB. My sister recently got her own car and her quote from them went from €1283 to €875 with her 2 years as a named driver on her husbands car. If she had a 2 ncb in her own name the price would have been approx €820, so you can see they give almost as big a discount for named driving experience.
Thanks for all the info. I have done some more ringing around and got a quote from €860.00 to my latest one which I find hard to believe, €300.00 Fully Comp. They are giving me five years NCB for being a long term named driver. I got the quote on Friday and I am waiting for it in the post on Monday. If it all seems OK I will give the details here for others in the same situation.
