Unlike too many cars (and people) with ill-fitting speedos, the GT's is about right, with a maximum figure of 220 mph. High-speed testing at the Nardo track in Italy during the GT's development had it going between 208 and 212 mph over the course of several runs. Ford certified the car as a 205 mph vehicle because they were confident that, even with production variances, all Ford GTs will be capable of at least 205 mph. If you go on various supercar/video Web sites you can ride along as people "test out" their exotic's speedometer, and I've personally seen video of a guy in Germany doing 218 mph in his GT on the autobahn (he had the camera mounted between the seats)...

What's the fastest speed you've ever reached in your GT?

Easy -- that was %#$ mph. Wait, did that get garbled? Let me repeat. I've hit &^@ mph in the GT.
What's wrong with this thing?!

Give me a GT with a twin turbo conversion. Ive seen a video where a guy (Joe) had the conversion done and put down over 1000hp AT THE WHEELS but the best part is that its still civil, smooth and the conversion hasnt dimenished its reliablity. The only vehicle that beat the car on the street were 2 built/modified Hayabusa's, impressive indeed!

Dang, so he dumped all that money into a GT, voided its warranty, and still got beat by a Japanese bike that anyone with a job flipping burgers could afford. Ouch!
