 I have a 1992 300E and 2004 E320 both 
are black int and black ext.  The 2004 
has better technology and power (of 
course).  As far as quality and ride, I 
like the 1992 better. My 1992 has 
better handling ad better quality 
material.
 So far I encounter 1 minor problem.  
The Nav system had problem reading the 
DVD.  After driving for 30 min, and 
turn off/on the car again.  The problem 
went away.  I am glad to hold out for 
2004 model instead of previous model 
(1996-2002).  The previous model got 
ugly tail light (personal experience).
