How many electric motors does your car have? My '87 740 has 27 (unless I can think of any more). Higher spec., newer cars should easily be able to exceed this.
1 x starter motor
1 x windscreen wiper
1 x rear screen wiper
2 x headlight wipers
2 x screen wash bottle (front and rear)
1 x radio aerial
1 x cassette player
4 x window motors
5 x door/tailgate lock motors
1 x heater blower
4 x door mirror motors (2 in each)
2 x fuel pumps
1 x electric clock
1 x LPG/petrol actuator (as per conversion to LPG)
Sometime soon I may be fitting one to the sunroof. I've not counted the speedo or rev counter, though I suppose these could be included on a technicality.
