Your comparing two porsche's. Do you want the $850 porsche or the $630 posche. Debating the best color to get your choice in would be easier. X-ray by a nose only because it's already out and hidden issues have been exposed. Hidden issues will be found in the MP9 every buggy has issues including X-ray read the 808 thread. Not major issues but issues all the same. Besides you could already have your X-ray on the track like yesterday.
