I got to drive a new C55 AMG today. And WOW!

Talk about driving pleasure. Now please don't crucify, I know a lot of people don't like AMG's because of the so called "slushbox", but if you have ever driven one I would like your opinion. It's a lot quicker than my M coupe. I personally don't mind driving a auto when it has ridiculous amounts of torque (510 lb-ft). I don't think I have ever had so much fun driving any car. Shifts are smooth and fast, 0-60 is supposedly around 4.5!! And it feels quicker that that.
I would think if someone was looking for a highway cruiser this car is ideal. Here in Florida that are not many twisty canyon roads, or any twisty roads for that matter. I feel like my M coupe is wasted on the highway and that I don't get to experience it's true assets.
So.......besides the "slushbox" is there any reason more M3 drivers don't go the AMG route? Who has driven a AMG and what did you think?
The AMG C55 is nearly the same price as the M3, so that would not be a reason.
Please don't flame me, BUT after driving it today it just got me thinking to myself "This thing is freaking awesome!"
