After almost 7 years in development, BMW introduced the second generation of the 7 Series, known internally as the E32. Aimed at the high end of the luxury market, the car offered some of the latest innovations in automotive technology, and a new, top-of-the-line V12 engine. Some luxury options featured on the E32 included integrated telephone and fax machines, a wine cooler, double glazing, traction control system, and a system that automatically increased spring pressure on the windscreen wipers, to keep them firmly pressed on the glass at Motorway speeds. The E32 (750i) was the first car adhering to BMW's self-imposed speed limit of 250 km/h (155.37 mph).
The car was also available in a stretched version (indicated by an 'L' from German Lang, after the model number), in which case an extra 11.4 centimeters (4.5 in) of leg room was available to the rear passengers by stretching the rear doors, and the body at this point.
The BMW 750iL Highline was the top-of-the-line model of the E32, with lots of added luxury for the rear passengers like full leather, dual radio controls, dual climate control with coolbox mounted in the center console, electrically heated and adjustable rear seats, walnut veneer folding tables, two crystal glasses neatly placed in the coolbox, leg rests, and sun shade all around the rear/side windows. Complete with independent heating and ventilation, it also added a second battery in the trunk and a second alternator to provide power for all these luxuries. The option package cost more than $13,000, and was only available on the 750iL, bringing the total price to well over twice that of a 'basic' 730i.
