Yes guy, I ended up buying the car. It is a 2009 Mercedes Benz Bluetec - V6 - 24 Valves - Diesel engine. The has 151K and had only one owner and it is in a excellent condition.
I drove it home and it has a smooth ride and it is extremely comfortable.
Up to now I am happy with the car and also with the purchase that I made.
Thanks all for the advice's and now is only take care of the car.
Thanks
