About me

career experience

This classic car expert valuations service is run by John Glynn. Born into a family business on the west coast of Ireland, I completed several years of a mechanical apprenticeship with a local car dealer before moving to London in 1989 to chase my dream of becoming a motor journalist.

That dream eventually became a reality. Along the way, I found that my passion for older cars and a penchant for economics and sociology intersected in the dynamic world of car and motorcycle valuations. After many years in the motor trade, I spent ten years with Glass’s Guide – the UK’s most respected provider of valuation data  – before striking out on my own and focusing on my freelance consultancy work.

  • Experienced classic car and motorcycle collector and restorer

My expertise in classic car and motorcycle valuations is underpinned by extensive market intelligence and a deep insider’s knowledge of how the motor trade operates. Over three decades of market valuation experience gives me the credibility that matters in case disputes or in Court.
