About this car

This 2023 Kia Stonic GT Line S has covered 18,833 miles. Our estimated market asking price is £16,070. This car is advertised at £15,995, which is £75 below that figure. To estimate its market asking price, we analyse UK dealer adverts for 1,689 Kia Stonic cars across different ages and specifications. Since we first spotted the advert 66 days ago, the asking price has dropped by £1,000. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 24 May 2027, and the latest recorded mileage is consistent with the advert. The seller is JCB Group Ashford Orbital Kia, based in Ashford.
