Salaam,
Well it seems to be a decent offer. Someone offered me the same model for AED 79,000. If you are satisfied with the car then well and good, go ahead and buy it... you can also send one of your friends to the same seller and see what price he offers him. Worth a shot for such a car. Believe it or not I have seen some sellers offer really less ... once you buy such a car, all sorts of problems appear in the car which you cannot tell at the time of purchasing!
