Hello,

Far the worst feature of the W 124 is certainly the flat mirror on the driver's side. As Freestyler stated before : you can hide a full size truck in the blind spot. My former car, a Volkswagen Passat wagon had the same illness.
But VW offered an "aspherical" mirror as an option (about $ 40 at that time).
Helas, for the W 124 it doesn't excist...
The aftermarket must have known this because overhere in most partshops you can buy rather cheap an aspherical mirror to be glued on the original one.
Offcoarse, some of the heating capacity is lost but it is adding a lot of safety.
