Just to clarify (we had a discussion, about the CSL options, at the coffee-break at work and I had some difficulties to convince the girls in the secretariat), these were the official list of payable options for the CSL (price in brackets):
Carb version:
No options list. However, clients could ask their lokal BMW dealer to instruct the factory to deliver their new CSL directly to Alpina for the B2-S modifications. At Alpina in 1972, Hans-Jurgen Pagel took good care of these administrative arrangements.
LHD injection and the first series of bat (production codes 3451 and 7071) - options list as from June 1974:
Motorsport-strips but only for Chamonix and Polaris (free of charge)
Rear 2-point interia reel safety belts (131 DM)
Head light wipers/washers (397 DM)
Second wing mirror - right side (26 DM)
First aid kit (34 DM)
Warning triangle (13 DM)
Metallic paintwork (680 DM)
Velour carpets front & rear (105 DM)
Lockable petrol filler cap (17 DM)
Large tool-kit (148 DM)
Power steering (815 DM)
Power windows (547 DM)
Tinted heat absorbing glass with laminated windscreen/Verbundglas (392 DM)
AC + tinted heat absorbing glass with laminated windscreen/Verbundglas (2727 DM)
CS/CSi bonnet lock - from inside (59 DM)
CSL Radios:
Becker Europa with automatic Antenna (730 DM)
Becker Grand Prix with automatic Antenna (950 DM)
Blaupunkt Bamberg CR Stereo with manuel Antenna (1090 DM) or with automatic Antenna (1330 DM)
Town kit:
standard CSi chassis with steel doors, large tool kit in luggage compartment lid, power rear windows, CS/CSi bonnet lock, power steering, CS/CSi velour carpeting and color stripes (black, dark blue or dark green) along the sides.
Bat-kit for the bat cars:
this was a "free of charge" delivery on all bats, independant of the clients' wishes. In Germany it was delivered in the boot, but for most other markets it was allowed on the car. As from 1st of July 1973, the price of the CSL increased with 3000 DM. The common opinion, at the time, was that the increase in price was mainly because of the bat-kit.
Note 1: the first time the E9 options are listed, in a special printed leaflet and including the CSL options, is the 24th of June 1974. However the CSL-options were internally listed by BMW adressing their dealer-network via the so called "Schnell-Information" nr 6/72 (dated 9/8/1972).
Note 2: the last listing for the CSL options is the 25th of August 1975. The only two additions in 1975's list are the option for the stronger Battery 55Ah (41 DM) and BMW Bavaria radio with Antenna (473 DM).
Conclusion:
the first printed official "BMW Preisliste" leaflet, with the CSL included, I have seen is from February 1973. The CSL is listed for 32 700 DM, but not listed for any specific CSL options.
I think, as from June 1974, BMW were more specific with the options for the CSL ("Das BMW Sonderausstattungs Programm"). Before June 1974, it was, most likely, possible to request options from the CS/CSi list. Of course, with the exceptions that not all were possible for the CSL. Based on the experience, from what clients had requested before June 1974 as options for the CSL, it "shaped" the official and printed CSL-options list from BMW.
This means that most of the Injection CSLs, produced between September 1972 - June 1973 and the Bats produced July - October 1973, were equipped with the Town-kit (as it was a free of charge option) and a variation of individually chosen E9 options. The last batch of 57 Bats (1/1974 -10/1975 with production code 7071), were also most often equipped with the Town-package (as from 1974 a payable option) and various other options.
As regards the RHD CSLs, they had a different approach.
