The median is omitted below 20 cars with a plain price. These are prices sellers ask, not sale prices; mileage and equipment move the price, so present it as a guide.

Covers listings sellers published on AutoIsto directly and public listings from Slovak car portals. Pass the criteria as ONE short phrase in Slovak (Czech also works), with numbers as the user said them. Examples that are fully understood: \"škoda octavia kombi diesel automat od 2017 do 15000 €\", \"suv automat do 25000 €\", \"bmw x5 diesel od 2019 do 40000 €\", \"kombi do 10000 € Žilina\". Use at most ONE body type per call (kombi, SUV, sedan, hatchback, liftback, van, kupé, kabriolet, dodávka); for two body types make two calls. Leave out filler and wishes that are not filters (rodinné, auto, do mesta, spoľahlivé) and equipment (ťažné, panoráma) — unknown words are not applied and are listed in notUnderstood. Returns up to 10 cars with price verdicts, what was understood, which criteria were relaxed when nothing matched exactly, which words were not applied, and a link to all results. Limits: only cars currently listed on AutoIsto (Slovakia, prices in EUR); no new-car configurators, rentals, leasing offers or cars abroad; the offer changes daily, so a car may already be sold.",
