So I'm checking out car insurance deals online using all of the usual comparison sites. Cheapest I found was around £1,800. Disgusting.
Went through to purchase said insurance, added my partner as a named driver = £1,000.
Work that one out. And she's a terrible driver.
Tip: Don't accept the face value of a quote, do a bit of digging and look at other options, but keep it legit and legal. Do not lie on the application form.
