 The 2004 S430 is not worth the money.  
We have had problems that have never 
been corrected since the day we took 
delivery.  There is always a problem 
that can never be fixed, nor does 
Mercedes care to solve the problems.  
We are even told that the battery 
cannot support all the electronics in 
the car, so if you go on vacation, you 
better buy a voltage charger or assume 
your electronics won't work when you 
get back!  Moreover, Mercedes doesn't 
care about this or any other problem 
they know exists!
