 I've owned my S4 for over 30k miles now, so I think I can properly review it as a used car.  It's a blast to drive if you drive it like it wants to be driven. You honestly have to take care to drive it slowly.  I commute 3 hours round trip to DC everyday and while I hate my commute, if I just stomp on the gas in 3rd gear at 3k revs, it makes you smile like a teenager watching American Pie during a certain scene.  Gun it in first and you almost feel uncomfortable.  It throws you back and takes some getting used to.  I typically drive conservatively, but if you downshift in this car and hear the growl, it just makes you smile.  I give my car to my wife when I'm out of town, and it scares her.
