Here's an example of the conversation
Them : So we'll put your new car on temporary insurance.
Me : No, New car on insurance, old car on temporary until I can sell it
Them : Oh, sorry. How long do you want to keep your new car for?
Me : Er, forever.
Them : Let me just check something <on hold music>. OK sir, you want to switch your policy over to a new car on the 12th, and keep your old car until you sell it.
Me : Hallejuhah!
I was on one then, rang AA to complain why my renewal was £167, and new customers get charged £90. Down to £72 straight away. WHAT!!??
