my dad is thinking of getting a s 55. we have a s 430 and my dad already complained the steering being too light. will this be a problem on the s 55? it's a amg but it's still a s class....

2001-2002 S55 there's no difference. New 2003 S55 has tighter steering feel (less boost actually).

there is a lil steering difference between the s-500 and the s55 becuase of the more torque and the hp.......mb has improved the steering of the s55

I think you mean, AMG has improved the steering of the S55.
