Esti que ça me fais rire c'est osti de commentaires là qui arrête pas de revenir...I don't know how to say this gently... but those who can afford to buy a luxury vehicle don't worry about fuel mileage or fuel costs.
I think the size of that truck + diesel, makes total sense. But make sure you have a mechanic that can maintain that car for you that's NOT the dealer....
Is there anything to look out for in a Diesel Vehicle? Never had one before. I heard Mercedes Bluetec is very good.
