I have to ask if anyone here knows. Has BMW ever thought about doing a Diesel Engine for the LT line? They are the leader in Diesel Cars and I would be interested in something like this. You would not have to worry about the mileage any more and it would last even longer than its gas counterpart. If there is any company out there that can do it, it is BMW. This is something I have been thinking about for a while and had to ask about...
