The GT500 does seem like it was ignored this year other then a couple of minor upgrades the biggest being the new aluminum block which will save a little weight. Whats great about the GT500 is that it has an engine that is capable of producing even more hp with very little cash. Just like the 03,04 Cobra it can be easily pullied and tuned for another 100hp.
By the way, how can you compare the GT500 to the Mercedes or the BMW? The GT500 is half the price and with a set of slicks will dust both those cars.
If I had the money to go buy a new 2011 5.0 I would probably just buy a used GT500 instead.
