Every week a Guardian Money reader submits a question, and it’s up to you to help him or her out – a selection of the best answers will appear in next Saturday’s paper.

This week’s question:

What is a suitable gift for our grandson on his 18th birthday? We’d prefer something tangible rather than money (we gave traditional silver items at his christening). What do readers remember as their best 18th present? What do today’s 18-year-olds most want?
