 having had many large capacity german cars,the 2001 s430 i have owned for 6 months has to be the best,i usually travel from the top of the country to the west only stopping once,then walking from the car fresh.  if i can recommend anything the s430 makes a little more sense as slightly better fuel and tax economy, do not give a lot away in 0-65 times and nothing in the limited top of 155 mph, economy wise i have personally had 32 mpg a steady average on my frequent m74,m6,m5 journeys.  so to return that in this class of car should make you think twice as the price of a fmbsh car is cheaper than a second hand mondeao, any complaints about servicing,think about the car your driving!.
