Not trying to start an argument here, but perhaps it's more of a perceived difference, unless you had a modified one. I doubt any stock Euro will beat a GT, or even an S4 in any gear, or at any speed. 0-60 data for the 85 (manual) and up US 32V motors show times consistently at or below 6 seconds. Even the following official Porsche dealer promo video backs up the performance specs that I pointed out earlier for the Euro model. The specifications and performance begins at 50 seconds into the video. If you don't believe me, watch the video.
BTW, those specs mentioned in said video pertain to the EURO model - 0-100km (62MPH) in 6.6 seconds, and that's no where near the performance for the S3,S4, and GTS models. Sure, those specs show the Euro to be a bit faster than the 16V US models of similar years, but not that much for a supposed 70HP difference in the Euro-car's favor. I'd like to see actual (measured at a dynometer) and official horsepower and performance data for the Euro model, if anyone has that info. I think the Euro model is cool, but I was shocked and disappointed with its relatively dismal performance based on the data that is out there. It should just be a lot faster, because it's supposedly lighter, is equipped with lower/shorter rear-end gearing, and has at least 300HP. The physics just don't add up.

BTW, anyone have thoughts my original question about what years they predict will have the most demand/value?
