I have a Ford Fiesta. My 18yo son passed his test last week, so I've been researching options. I put our details into a comparison site and the cheapest quote was £1000, with a tracking device. But when I phoned my current insurance company (Direct Line) the quote to add him as a named driver was only £100, with no tracking required! 😯 Is this surprisingly low? There is an excess of £750, and he won't build up a no claims discount, but am I missing any other pitfalls? I'm about to accept the quote, but thought I should check first.
