The first cars were the 728, 730 and the 733i with the advanced Bosch fuel injection. The 732i was sold from 1980-83 and was replaced by the 735i. The 728 and 730 were discontinued in 1979 and replaced for three years by the 728i.
In spring 1980, the E23 added power locks, electric windows and tinted glass. The 735i gained a headlamp washer and wiper. In 1981, the five speed manual gearbox replaced the four speed unit as standard. The BMW service indicator board first appeared on this model, and ABS was available as an option. In 1982 the four speed overdrive automatic gearbox was introduced as an option and there was a new front spoiler.
All E23s were based on the M30 "big six" engine. All were 12 valve units except the South African version of the 735i. The 728 and 730 were the only non fuel-injection engine models. ABS was an option on early cars, not standard equipment.
Early cars only had a 4 speed manual gearbox or a three speed automatic. Later versions had a 4 speed automatic with overdrive. The L7 was a luxury version available only in the US with an automatic transmission. This car had a leather head lining, leather door skins, leather dashboard, etc.
