About the UK’s Most Experienced Classic Car Valuer

John Glynn Classic Car ValuerBorn into a family music business in Ireland in the late 1960s, my passion for cars ignited at a young age. Autocar magazine was my favourite, with writers like Steve Cropley and Phil Llewellin, who inspired dreams of working as an automotive journalist.

I began my motor trade career in Ireland, as a mechanical apprentice with a local Renault dealer. Balancing my apprenticeship by day and playing music by night, I soon realised that a writing career would flourish in the UK. At 19, I moved to London to pursue my dream of becoming a motoring journalist. I gained extensive experience across the UK motor industry, working with car dealers, finance companies, in retail and fleet purchasing, and selling hundreds of cars. But not writing.

After a decade in the motor trade, my desire to write about cars remained strong. An Assistant Editor’s position with Glass’s Guide—the leading motor trade publisher—caught my eye. I served a challenging apprenticeship under the Chief Car, Motorcycle, and Commercial Vehicle Editors, and supported by a brilliant MD, I spent over ten years running Glass’s Guide to Older Cars and Modern Classics, also developing and managing the UK’s first online valuations platform.

In 2003, I ventured to the south of France to buy my first air-cooled Porsche; a risky purchase that sparked a sideline in journalism. This led to the founding of an online community for Porsche 911 fans and a collaboration with an emerging photographer, culminating in our book, “The Cult of Porsche.”

A press release about a 1970s Cadillac I had bought and sold caught the attention of my boyhood hero, Steve Cropley. This led to my first commissioned feature for Autocar magazine, achieving my dream of becoming a car journalist. Following years of journalism, including a BBC Radio 4 appearance, I discovered my true passion lay in vehicle valuations. I founded my freelance vehicle valuations consultancy in 2004 and, in 2010, left Glass’s to focus on my own business.

Now in my mid-fifties, with over 70,000 hours of high-level market experience, I am the go-to expert for insurers, lenders, solicitors, and private clients needing impartial expert support in court. My extensive experience includes historic motorsport, co-owning Twinspark Racing, and over 15 years with Tuthill Porsche. I maintain long-standing relationships with UK fabricators, car preparers and classic car restorers and curate a personal collection of 17 cars and motorcycles.
