The car in question is a 2012 Mercedes GLK300 V6 3.6L Standard. We have an offer accepted for a 2011 GLK300 3.0L V6 at AED 28000. This car has a smaller engine and is a year older, but has significantly lower mileage at 88800 km. The listed price for the same 2011 model is AED 30500. Given the higher mileage of the 2012 model at 218500 km, we should expect a lower price. Considering the accepted offer and the listed price, and accounting for the higher mileage and slightly newer model year, a reasonable estimate for the 2012 model would be slightly above the accepted offer but below the listed price.
