no see the reasoning behind it is the power characteristic they desire from the motor. US cars use positive displacement superchargers on the v8s because people that buy a v8 here in the US like the way v8's snap, it's all about low end, high torque grunt that is driveable and acts just like a bigger motor. Most foreign import turbo cars have turbos because the people that buy them like the power coming on and feeling like it's going to keep going forever. highend track cars tend to use superchargers because of the same driveability reasons especially so in track duty vehicles because a supercharged car is much more controllable in a corner where as turbo cars have to worry about when the turbo's will begin spooling spinning the rear out. Superchargers aren't found on most import vehicles for another reason and that is the displacement tax and fuel economy regulations. Plain and simple a turbo is more fuel efficient, so if you are trying to up the power without having to levy a higher vehicle tax class a turbo is a better way to go. Of course when your talking about AMG Merc's do you think a guy that can buy an $80,000 car gives a rats @$$ if he has to pay 1000 a year more because it guzzles fuel? they want driveabillitiy and power they can take to the track, not an unrefined rocket that hits 3200 and takes off like it has a mind of it's own.

Edit: OEM's could careless about people who mod their cars as the percentage of owners is low, it leads to higher warranty costs, and proof enough of that is that they keep making the ecu's ever harder to crack and their proud of it. not to mention that in most places modifications like upping a cars boost is illegal if not in a legal grey area. They have divisions like GMPerformance parts, Nismo, TRD, Ford Racing, to take care of the users that do feel like modifiying their cars so in initial design there is little to no consideration to that point. Look at the oil cooler issue with nissan, the car is equipped with big brakes and a track minded transmission, and 332hp, it gives the image of a real track car which is what sells cars. Then you find out that they don't really care wether you track it or not because most people won't, so it doesn't matter to them if the brakes fade right away, or the engine over heats (making you look like a B*tch on track) they will just say it wasn't intended to be used that way, even if they market the car differently.
