My (multicar) policy always renews in early January, which results in the same, slightly unnecessary, game play of a hiked renewal, a poker-like game play on the phone, and a magical reduction from the original excessive quote.
This years game with Admiral was on a 35 minute phone call, which shaved just over £310 off their initial quote of £1190 for my 4 cars, including my S8 (which was a 22% increase on last year, with no real logical justification)
An annoying way to spend ah hour in the first week of the New Year, but at least it didn't take too long this year...
