About Bimmer.AI

Why Bimmer.AI exists

Buying a used BMW in the UK right now means juggling AutoTrader tabs, Bimmer Post forum threads, HonestJohn owner reports, DVSA MOT history, YouTube reviews, and engine-specific reliability articles — 12–14 tabs per listing, 30 minutes to decide whether the car is worth travelling for, and a real chance of still getting it wrong.

Bimmer.AI collapses that workflow. Paste any BMW listing, VIN, or registration — get the engine identified, the known failure modes for that engine, the recalls that might apply, the UK repair-cost exposure, and a buy/negotiate/walk verdict. In about 30 seconds.

We built it because we needed it. A year of searching for a 530d Touring for a growing family proved conclusively that the knowledge exists out there, it's just scattered. Bimmer.AI is the collated version.

What we do

• Engine-specific buyer reports on any used BMW, triggered by listing text, VIN, or reg plate.
• Deterministic chassis × engine lookup so "which engine is in this 520d" is never a guess.
• Structured UK-focused failure database per major engine — currently N47, B47, N57, B57 diesels; petrol and M engines in development.
• Public reference content — engine guides, the chassis-code reference, pre-purchase inspection checklist, HPI comparison, methodology and sources. Hand-written, UK-focused, no AI content-farm output.
• Seller mode — same tool flipped to generate listing copy and answer buyer questions for private sellers.

What we don't do

• We don't replace a physical inspection. Bimmer.AI is the first filter and the negotiation-prep tool, not the workshop-level verdict.
• We don't replace an HPI Check. See our HPI vs Bimmer.AI comparison — provenance checks are a different layer.
• We don't handle non-BMW brands. BMW-deep over brand-wide is a deliberate decision. If we can't tell you more than a generalist site, we shouldn't bother you.
• We don't fabricate reviews, ratings, or testimonials. Empty sections are allowed.
• We don't overclaim on AI. The model is used for language and synthesis. Engine facts, failure patterns, and cost ranges come from structured internal data — see Methodology.

Who built it

Bimmer.AI is a small independent project, built by a UK-based BMW owner with a background in software. The written content is human-authored and reviewed. The technical stack is public — single-file React app for the tool, static HTML for the public content, Cloudflare-hosted throughout.
