How much would it cost to insure a car?

I'm thinking about getting a 1998 ford fiesta from gumtree its £400 for the car and I'm 19 years old and I'm wondering how much would it cost to insure it

It will be £12.8883856 and a few odd slotskies. It is always £12.8883856 and a few odd slotskies. I'm surprised that you didn't know that?

The gene pool could use a little chlorine

Insurance will probably cost more than the car does. Pick up a phone and call a local insurance agent to find out.

That will depend on your age, driving history, post code and type of vehicle.

It will cost a lot. Way more than the car will cost, for sure. Something between a king's ransom and holy Jesus you're kidding is a fair guess.

If you want an answer that isn't a guess, something with actual numbers in it, you'll have to call an insurance provider or six and ask for a quote. They'll need a few more details than you provided here, but they'll tell you.

Don't bother with online quoting at your age, it's a waste of time. There are hundreds of sites that offer quotes from multiple insurers online, and some of them are even legitimate. Most are not. You'll know when you've found a legitimate site when you spend 30 minutes keying in all your info and get a screen that says "sorry, we couldn't complete your request, please call for a quote". They do that on purpose.

Call some insurers.
