EC71 = 635CSi, euro market, high comp motor, manual tranny.
In similar manner:
DC71 = M535i, euro market, high comp motor, manual tranny.
Here's is *generally* what the codes stand for:
E stands more or less for E24
D stands more or less for E28
C stands for 3430cc M30
the first number usually stands for the engine/tranny choice (e.g., 5 = low compression, manual; 7 = high compression, manual
the second number stands for the market (e.g. 1 = europe, 2 = UK RHD, 4 = USA).
But US cars only had low compression, and their # codes are 74 and 84, so it is inconsistent with the european codes. That's just how BMW did it, don't ask me why.
Usually, though, if you have a "1" as the 7th digit, it denotes european market, and a "5" denotes low comp motor with manual, "6" denotes low comp motor with automatic, "7" denotes high comp motor with manual, and you guessed it, "8" denotes high comp motor with automatic.
Hope this helped, rather than confused...
