Difference between the E420 and the E500..
im running 18X8 on my 420 and they look good, its a good size.
yes wider tires make a Huge diff. than skinny tires,
Mark
The 500E as wider fenders and quarter panels opposed to the E420. Which would allow for wider wheels and tires. Although, I have seen 500E's with 9.5 and 10" wide wheels in the rear.
Personally, I would like to consider the 500E a one of a kind and entirely different than the standard W124's.
Well, truth be told that the 500E has more in common, suspension wise to a R129 SL than a W124....really, all/any SL rims fit on the 500Es. And the brakes are SL500 or SL600 vintage depending what year.
Unfortunately, the regular bodied W124 E420 is limited to the rim width...but that shouldn't stop someone from widening or rolling their fenders to fit fatter stuff under there. The 420 can welcome the extra traction it provides.
