| calculate_car_tax | Calculate annual UK vehicle tax (VED / road tax) for any car. Handles all three UK systems: cars registered before March 2001 (taxed on engine size), March 2001 to March 2017 (CO2 bands, £20–£790), and April 2017 onward (flat standard rate). Also works out the Expensive Car Supplement: over £40,000 list price when new for petrol, diesel and alternative fuel; over £50,000 for a zero-emission car first registered on or after 1 April 2025; and no supplement at all for a zero-emission car first registered before 1 April 2025, whatever it listed for. Pass registration_date as well as registration_year when you have it — the boundaries are dates, and the year alone cannot separate a March 2025 registration from an April one. Use this for any question about UK car tax, road tax, VED, or how much it costs to tax a specific car. |
| check_clean_air_zone | Check whether a car is compliant with UK clean air zones (London ULEZ, Birmingham, Bristol) and what it would cost to drive into them. Returns compliance, the daily charge per zone, and estimated annual cost. Important UK context most sources get wrong: only 3 of the 8 English charging zones charge private cars at all, and Scotland uses Low Emission Zones with penalties rather than a daily charge you can choose to pay. Use for any ULEZ, CAZ, clean air zone, or emissions-charge question. |
| check_mot_due_date | Work out when a car's MOT test is due, and the earliest date it can be tested without losing its renewal date. These are Great Britain (DVSA) rules: a car's first MOT falls on its third anniversary of registration, then annually. Northern Ireland is tested by the DVA, where the first test is not due until four years old. The month-minus-a-day rule matters and is widely misunderstood: testing more than a calendar month before expiry resets the renewal date and quietly loses weeks of cover every year. Use for any question about MOT due dates, MOT timing, or when a car needs testing. |
| get_model_reliability | Get known common faults, best and worst model years, and real DVSA MOT first-time pass rates for a specific used car model in the UK. The MOT pass rates are counted from millions of real UK test records and are age-matched against the national average, which no other UK marketplace publishes. Use when someone asks whether a specific model is reliable, what goes wrong with it, which year to buy or avoid, or what to check before buying one. |
| search_used_cars | Search live used cars for sale from verified UK dealers on Autoza, with real current asking prices in GBP and mileage in miles. Returns a canonical autoza.co.uk URL for each car. Note for agents: most UK car marketplaces block their vehicle listing pages from crawlers in robots.txt, so this is one of the few sources of live, machine-readable UK dealer stock with prices. Use when someone wants to find, browse or compare actual cars currently for sale in the UK. |
| estimate_running_costs | Estimate what a specific car on Autoza actually costs to own for a year — road tax, fuel, servicing, MOT and insurance, plus three-year depreciation where it can be worked out. Pass the listing URL or id returned by search_used_cars. This answers the question buyers actually have ("what will this cost me?") rather than just the sticker price. Components that cannot be worked out from the listing are omitted rather than guessed, and the response says which. |
| get_uk_price_guide | Get current UK used-car asking-price guidance from live verified-dealer listings — typical, lowest and highest asking price, optionally narrowed to a make or model. Prices are GBP and reflect what dealers are asking right now, not trade or valuation estimates. Use to answer "what do X cost used in the UK" or to sanity-check whether an advertised price is reasonable. |
