I was trying to add the RX8 to my multicar policy the other day and, after several calls to Admiral got a price of ~£450 for 7 months (up to the renewal date of the whole policy) which equates to £770 for the year.
An online quote from Admiral for a year was £480..
I called back and the unhelpful lady gave a response of "We can't change the price. The price that you've been quoted is the price."
So another online quote and this time it was Diamond "For Girls" who had the best price with Amy as the main driver and me as named.. part of the same group of companies (Admiral, Bell Direct, Elephant and Diamond).
I called them up and this time the fella at the other end couldn't have been more helpful; in the end we rolled all of our cars (Omega, M3, RX8 and Amy's Micra) into one multicar policy and dropped the price of the RX8 insurance down to ~£400 for 12 months and the predicted renewal price of all the other cars dropped as well with a total saving (vs the original ~£700/12 months on the RX8) was about £700 across all the cars.
With the same company!
Madness and really shows the difference in quality of call centre staff..
