Yes sir, these are some rare cars and all made possible by Rudy who is by far the best MB mechanic out there. Working with others around the globe to make the XF one of the fastest in it's price range. I can say a V8 is never out of the equation for me, but I first want to run a legal NHRA race in a stock class specifically for the XF. Once that is done, maybe a V8 black roadster to set next to the coupe. Congrats on your build, and a great article.
