Any question answered...

Learner policies are usually about 2/3rds the price of the policy on a full license. As someone who's 18yrs old you're looking at paying a minimum of £1000. He'd be better off in something like a Citroen C1 or a Chevrolet Matiz. Newer cars tend to be cheaper to insure due to the increased safety measures.

A car I bought for £100 costs me £800 to insure with 2yrs no claims.

The good Mrs Savage has a Peugeot 107 he will be insured for but he wants to spend his money on an old banger and he won't be swayed at the moment. We'll see.
