Which one to buy????
As much as I'd love a rocket, this will be an everyday car, much around town useage. I am looking for something that is sharp looking, a wee bit zippy, will get high miles,etc. (hey-asking a lot, but I know M.B.'s fit this bill)
Longhaul

a W140 3.2 will prob do 25mpg - but it weighs two tonnes - so isnt nippy...

the 4.2 has 275 bhp, and isnt too bad off the line, but is definately a ?interstate? / ?highway? autobahn / motorway cruiser. the steering is very light, so is easy to park
get a post 1996 car (identifiable by side air bags and probably proper electronic parking sensors - a must! )
I get 22 mpg in my coupe (4.2) - called a CL420 - i think you guys didnt get the 4.2 option - only the 500 (5 litre !)
Then the car that would fit the bill is last year or so w140 s320 lwb....
1999 last year ,or maybe 98 ..because they the earlier problems in the early years of w140 were addressed.
The Long wheel base s320 looks exactly like s500 or s600... so a big car as well..
Since its s320 v-6....it better fuel economy then s420,s500 or s600
With your budget you can probably get 97 s420 or s500 as well, but i think the s320 will fit the bill and you probably get the last year and with fewer miles...
i bought , owned, and sold many w140's ....and infact i just bought 95 s320 lwb ..yesterday...and its still powerful enough to a have a zipp to it like an s500 or s600....
good luck
First the S320 used the M104 I6 not the M112 V6. The M104 is a great engine but the head gaskets do blow the were weak from the factory.
The S420/500 used the M119 V8, probably one of the best V8's every made, the oil tubes would blow their end caps off on the early models and make a lifter ticking sound. Not a big deal and cheap fix. Also they do not require timing chains to be replaced at 100k miles like the older M116/M117. An M119 timing chain is probably good for 300k+
Now the S600, wow their is nothing like a V12 powerd MB. It cost $150k new and it reminds you of that when things break. You have to have a "money is no object" attitude with these.
Also don't forget the S350D, the engine is sweet. But just get one with the updated engine because these are rod benders. However since it is a diesel fuel mileage will be very good. If the engine goes south $13k.
With any W140, make sure the evap has been done. They will go south eventually and it is a $3k job.
Mid 90's versions had the bad wiring harness. $500
It is a W140 expect to have a few problems, and spend some money.
