Well, here are my reasons to get an X5M:
1. I want the best handling SUV. I really doubt that the diesel version will have the same handling.
2. I am buying an X5M, so the fuel mileage is my last concern.
3. I also want the fastest SUV, and I also doubt that diesel version will match the 1/4mile of the X5M
4. The price of diesel fuel is higher than the premium where I live, so even if I did consider the mileage as an advantage then I'd have to drive a lot of miles to make a difference. But, according to my 2nd reason, I am not worried about this.
5. The price of the X5M. As I was building on the
www.bmwusa.com different cars to compare the prices, the fully loaded X5 50i to my liking was approaching the price of the X5M!!! So, I thought to myself, that's ridiculous, why just then not get X5M. I have no idea on the pricing of the M diesel car, but, honestly, since I am set on the X5M, the price is irrelevant.
6. Lastly, the M diesel car is not an official M car, so it would not make it as special, for me personally, as the X5M.
Having said all that, whoever will buy the diesel M will likely be happy with the car, but it's just not for me. I will certainly respect anybody's purchase, as all of us are car enthusiasts afterall. I am not at all trying to discourage anyone from buying it, or saying anything negative about it. Just my personal preference for the X5M.
So, hopefully this car will sell well, and not be a disaster like the X6 hybrid. Time will tell...
