Yes in theory but it doesn't always work out like that in practice, my own older Benz was group 18/19 iwhen i first bought her when they maxed at 20, cheap as chips to insure.

As i said before, you won't know till you get the quotes, from your own insurer (this is the moment you find out what your present insurer is really like) and via a search engine or two.

"Surely a group 20 will cost more in premiums than a group 10?"

For any one particular insurer, probably yes.

But a Group 20 car for Insurer A may cost less than a Group 10 car for Insurer B.

>Groups don't necessarily mean higher premiums<

This doesn't sound logical. Surely a group 20 will cost more in premiums than a group 10?

The steps between the groups are likely to be fairly small. But as GB says the onlyy way to a definitve answer is a call to your own insurer.

Alternatively a comparison site will give you a good idea.

Depends on the insurer and car. My brother found it cheaper to insure a group 6 2L diesel Peugeot 306 than a Group 1 1L petrol Corsa.
