crazybrit, smaller cars are more practical in big, congested cities like London. It actually makes a huge difference.
And yes, the E63 AMG Black is a monster. I love it, and it sounds amazing! Have you seen what Brabus have done with it? I’d take an E63 Black over the SLR any day.
But how is any AMG “practical”? In general, German cars are not known for their practicality (aside from VW), rather for their performance.
