About CarBuyerIQ
Smarter car buying,
powered by data
CarBuyerIQ is a vehicle intelligence platform that gives every used car buyer the knowledge they need to make informed decisions. We combine official government data with AI analysis to turn complex vehicle histories into clear, actionable advice.
Think of us as the knowledgeable friend you wish you had when buying a car — except ours has read every MOT record in the country.
Our Mission
The used car market is stacked against the buyer. Sellers have more information, dealers have more experience, and most buyers are left guessing whether they're getting a fair deal or inheriting someone else's problems.
We exist to level that playing field. By making vehicle intelligence accessible, free, and easy to understand, we give every buyer the confidence to negotiate from a position of knowledge — not hope.
What We Do
Three pillars that make buying a used car less of a gamble.
Vehicle Intelligence Reports
Enter any UK registration and get an instant, AI-powered analysis of the vehicle's full MOT history, mileage patterns, risk flags, and fair market value — backed by real DVLA and MOT data.
379+ In-Depth Guides
Our research library covers specific makes, models, and years with data-driven insights on common problems, running costs, depreciation curves, and what to look for when buying. Every guide is backed by real MOT statistics.
Negotiation Scripts
We don't just tell you what's wrong — we give you the exact words to use with the seller. Our negotiation scripts are tailored to each vehicle's specific history, so you walk in informed and walk out with a better deal.
Meet Dave
Your AI-powered personal car advisor
Dave is CarBuyerIQ's AI car expert — your personal advisor when buying a used car. He's built on advanced AI technology and trained to analyse vehicle data the way an experienced mechanic would, but with the ability to cross-reference millions of MOT records instantly.
Dave reads the full MOT history of any vehicle, spots patterns that humans would miss — recurring brake advisories, mileage anomalies, creeping corrosion — and translates it all into plain English advice. He tells you what the car is really worth, what to watch for, and gives you a tailored negotiation script with the exact words to say to the seller.
He's straight-talking and no-nonsense. If a car is overpriced, he'll say so. If it has hidden problems, he'll flag them. Think of Dave as the brutally honest friend who happens to know everything about cars — and who's always on your side.
Transparency note: Dave is an AI assistant, not a qualified vehicle inspector or mechanic. His analysis is based on official DVLA and MOT data and should complement — not replace — a professional vehicle inspection before purchase. We believe in being upfront about what Dave is and what he isn't.
Our Data Sources
Everything we do is built on real, verifiable government data — never guesswork.
DVLA Vehicle Records
Official Driver and Vehicle Licensing Agency data including registration details, tax status, and vehicle specifications. Accessed via the DVLA vehicle enquiry service.
MOT Test History
Complete MOT test records from the DVSA MOT history service — every pass, failure, advisory, and mileage reading going back years.
MOT Bulk Statistics
Aggregated MOT test outcome data across millions of vehicles, published by the Department for Transport. This powers our model-level reliability comparisons and failure rate rankings.
AI Analysis
We use advanced AI models to analyse patterns across vehicle data — identifying risk factors, predicting likely issues, and generating personalised advice. The AI interprets the data; it never invents it.
