Since we first spotted the advert 67 days ago, the asking price has dropped by £500. That history is worth bearing in mind when speaking to the dealer. The latest MOT record shows an expiry date of 1 June 2027, with the advertised mileage consistent with the recorded reading. You can find this car at S James Prestige in Stamford.
