2-3 second delay?!?
Coming from a turbo s2k, my 335 doesn't seem as responsive, but it has almost zero lag and instant torque whenever I need it to pass someone with no delay. I have a 6MT so I can't comment if your car was an auto that you test drove, but unless you were in the wrong gear i've never experienced anything like that before. Like all turbo cars, if its 90 degrees out and your engine is heat soaked, then driving off easy from a stand still then the car will have some noticeable lag, but that's about it really.
