I should probably give them a shout out. I contacted my old insurer Admiral and basically negotiated a deal with them.
They gave me their initial quote and I said "I had my Toyota Celica insured with you a few years back and rocked up 7 years no claims. So, I'll come back to you and most likely stay with you again if you'll beat every other quote I've had and do me a deal...don't beat it by £50. Beat it by a lot and I'll take it."
After chatting to a manager for about twenty minutes, I've saved myself £400 by negotiating with Admiral.
Got to appreciate when a company will bend & flex to make you happy. So, the premium is still a bit high at £830 but most other quotes were £400-£500 more than that so I suppose I'm happy.
