Here's my $0.02.....
I'm in the military and have been overseas (Germany) for most of my career. I purchased an 04 GTO and I love it!!! I've done some mods to it and I must say there there isn't a car over here that cost's less than $100K that can beat it on the autobahn. One thing that I don't understand is why there are soooooo many fast cars in the states and we have the most restrictive speed limits in the world!!! Here in Germany, you can drive your car as fast as it will go. I've had my GTO up to 177mph (as indicated on my GPS) with much more pedal to spare. I will post the video of me leaving an AMG mercedes way behind on the A6 autobahn as soon as I figure out how to do it. I would love to see a Mustang do that.
I've installed the Magna charger (complete kit), done some head work, bigger brakes, AGX gas shocks, Eibach lowering springs, 275zr 35/18's rear and 255zr 40 18's front, and a Corsa exhaust system, and the program that came with the magna charger.
One thing I do love about Germany is that you don't see any of those little "Fast and Furious" wanna be cars over here!!!!
