Hi everyone,

Considering on getting a W140 but haven't decided between a S320 vs S420 vs S500. The curb weight of the S320 is 4500lbs where as the S420/S500 are 4133lbs. This and the engine size are the key differences I see. If you're an owner, I'd like to hear your experiences with your W140, power, comfort, maintenance issues, etc...

Thanks!

 

The S420/S500 should be heavier than the S320. That is unless you're refering to the S500 coupe.

1998/1999 stats

S500 315hp 347lb-ft 15/21 mpg 4700lb

SWB Wheelbase: 119.70 Length: 201.30
LWB Wheelbase: 123.60 Length: 205.20

Cargo Space: 15.60 cu.ft
Passenger volume: 108.10 cu ft SWB 112.40 cu. ft LWB

All engines are DOHC
24 valve for inline six (S320)
32 Valve for V-8 (S420/S500)

 

Thanks for the correction. The specs that I looked at on autotraders for the S420/S500 must have been incorrect. It seemed abit odd that the 420/500 would have a lower curb weight.

Have you driven any of the three?
