VERY nice I must say, mashAllah. Can't wait to see the pictures, what color is it? The price seems very good, considering the fact it's a 4.5 grade vehicle as per what you have been told. Please do get the car verified before dealing, you may never know what the reality of the car is.
BTW, what are the Al-Hamd container and Gold Sea Port charges? Didn't your B/L contain the shipping charges?
In 14,50,000 you could have imported a 2007 G-selection with low mileage. But, you're going to be driving a '10 face-lift which is rare on it's own.
