Your 78 300D has a 3:46 Differential ratio
Your 83 240D has a 3:69 Differential ratio.
The 240d is a lower ratio, which means the RPM will be higher than the RPM`s of the 300D at the same speed.
The lower the number of the Differential gear ratio, the higher geared it is.
The 240D`s all used a 3:69, but the last year of the W123 MB used a 2:88 ratio which is way higher.
For every time the engine rotates 3.69 times, the rear wheels go around one time.
For every time the engine rotates 2.88 times, the rear wheels go around one time.
The low geared rear ends will get you off the line quicker, but the engine will be racing at the top end.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works
