Specialist Car Valuations: UK Independent Expert Car Valuer
About Specialist Car Valuations
John Glynn - Independent Car Expert Valuer UK
Proven Valuations Expertise
My motor trade history dates back to 1986, and includes more than three decades of professional valuation experience, hundreds of articles in the UK motoring press, a book on classic Porsches and media appearances including BBC Radio 4.
I spent ten years as Valuations Editor with UK motor trade price bible Glass’s Guide, where I managed and developed several vehicle Guides and a number of groundbreaking digital products, including the first ‘We Buy Any Car’ online car valuation algorithms.
I am the only independent vehicle valuer endorsed by leading UK insurers including Adrian Flux, Footman James, Classicline, Carole Nash, Locktons, NFU, REIS Motorsport Insurance and Performance Direct. I have served banks and insurers as their Expert Witness in court.
I am a member of the UK Register of Expert Witnesses. My valuations are accepted by HMRC and relied upon in civil, family and criminal court cases and in high-value legal proceedings.
My experience spans the full spectrum of the motor trade. I have bought, sold, written about and valued everything from early classic cars to supercars, veteran motorcycles, racing cars, vintage tractors, motorhomes, cherished plates and more.
I have extensive experience in historic motorsport, as a previous co-owner of Amsterdam-based Twinspark Racing, over 18 years with Tuthill Porsche including marketing and car sourcing and long associations with UK classic car restorers and repairers.
Well known for my Classic Motorcycle Valuations and Classic Car Valuations, my honesty and integrity means that most customers are repeat clients or referrals. I consult on valuations for all sorts of vehicles. I deliver detailed, independent expert valuation reports for solicitors and other professionals, regardless of case complexity, based on decades of professional valuation experience.
Contact me to discuss my services. I work with absolute discretion and your privacy is assured.
My Valuation Process: never AI and always in person
My valuation reports are created entirely by me with no AI data and always to the highest possible standards. I do not advertise: professional integrity and high quality reporting is why most of my work is renewal or referral.
Step 1: Initial Expert consultation
Discuss the situation, establish scope, and determine the most proportionate approach.
Step 2: Evidence-Led Valuation
Desktop or inspected valuation using market data, condition analysis and specialist knowledge.
Step 3: Clear, Defensible Report
Independent, transparent reporting suitable for court, insurers or private use.
