What is actually in it
Everything you need to price the whole journey.
All four VAT regimes
Margin scheme, VAT-deductible, intra-community reverse charge, and the fiscally-new trap under six months or 6,000 km.
It reads the seller’s own words
78 negation-guarded patterns read the description, so kein Rost and Rost are treated as opposite facts. Every hit is quoted back.
Three languages, light and dark
Full English, German and French interface. Seller-facing German phrases remain German in every interface language.
Known-issue database Starter
45 engine families and 137 catalogued faults, with symptoms, pre-purchase checks and destination-market context. The snapshot inside the extension works forever; staying current between releases is Pro.
l’argus valuations Starter
The French trade reference for the exact model and year, alongside the comparables your own browsing collected — a second opinion on the resale side of the sum.
German market comparison Starter
Whether the asking price is high or low against comparable German listings — a check on the source side to sit alongside the French destination numbers.
Negotiation kit Starter
Opening offer, target and walk-away, with leverage ranked by strength, copyable German phrasing, and the car-park checklist in the order that finds expensive problems first.
VIN lookups Starter
Pull real CO₂, kerb mass and engine code from the VIN, then flag contradictions against the listing.
AI second opinion Starter
For models outside the knowledge base, with an explicit instruction to identify where it disagrees with the local analysis. Runs on Claude Haiku 4.5 through our proxy — no API key to bring, no model picker.
Repair cost breakdown Pro
The whole repair budget: totals, worst case, and the parts/labour split per fault, with declared faults kept separate from probability-weighted risk.
CT forecast Pro
See which admitted faults will fail the French contrôle technique, graded by the 1991 nomenclature — the ones that block registration, not just the ones that cost money.
Known-issue database updates Pro
New engine families and revised repair figures as they land, rather than only what shipped in the version you installed.
Live parts prices Trade
Real prices from a parts retailer for the exact parts a repair needs, instead of a catalogue range.
CSV export Trade
A week of priced listings as a spreadsheet you can sort by margin.

Questions
Which listing sites does Klakso support?+
mobile.de, AutoScout24, leboncoin and La Centrale, with more marketplaces planned.
Does my listing data leave the browser?+
Core analysis, comparables and settings stay local. Optional VIN, parts-pricing and AI services only run when you enable them.
Can I use Klakso without paying?+
Yes. The free tier runs unlimited deal analyses — the full landed cost, registration tax and VAT calculation, plus comparables from listings you browse. The hosted extras (AI second opinions, VIN lookups, l’argus, parts prices) start at Starter, because each one costs us money per call.
How is the French registration tax calculated?+
Fiscal power from CO₂ and kW, the regional rate for the department you register in, the halving at ten years, and the emissions and weight malus — including the age abatement most calculators forget. Every line is shown, not just the total.
Do I need an account to use the extension?+
No. The extension works on install with the free tier. An account is what carries a paid plan across your devices and where billing lives.
