Model overview

Model description

In an effort to freshen an aging albeit pretty design, BMW introduced its E23 7-Series cars to replace the 3.0S/Bavaria in the U.S. in 1977. The 7-Series 730i was the flagship sedan version.

Designed by Paul Bracq, the 7-Series expertly echoed the 6’s design, only with four doors. Unfortunately, the 7-Series used a low compression head with air injection, exhaust gas recirculation (EGR), and thermal reactors to meet U.S. emissions regulations, which meant the cars were markedly slower than the European models. The EGR and thermal reactors also produced more heat than the 3.0-liter, 176-hp six-cylinder engines could handle, which caused cracked cylinder head and warping.

Beginning in 1980, BMW introduced a Bosch oxygen sensor and a catalytic converter, which solved the car’s heat problems. In 1983, Bosch L-Jetronic injection was switched to Motronic, which was much more efficient.

In 1985, the engine size was increased to 3.4 liters and the model was renamed the 735i respectively. The boost in displacement resulted in 6 more hp and 19 lb-ft of additional torque. A front air dam made the cars look sportier, and more equipment became standard. A more luxurious L7 was available, as well.

Neglected E23 7-Series are easy to find, as their well-equipped and sophisticated set-up meant that standard repairs were often expensive. Today these cars are best to be avoided, as they will ultimately cost more in the long run. Earlier cars, due to their EGRs and thermal reactors, are usually last on the list for enthusiasts. As with any older car, be mindful of rust, and check with a mechanic before spending more than you can afford to lose.

Common Questions

The value of a 1983 BMW 733i can vary greatly depending on its condition, mileage, options, and history. Typically, you can expect to pay around $8,400 for a 1983 BMW 733i in good condition with average spec.

Many factors can increase a car's value including excellent condition, exceptional originality, a recent restoration, low mileage, unique provenance, desirable options, popular or unique color choices, and excellent maintenance records. Upgrades and modifications that enhance performance or aesthetics can also add value.

Factors that can decrease a car's value include unusually high mileage, poor maintenance history, visible wear and tear, accidents or damage, title issues, and gaps in ownership history. Additionally, less popular color choices and extensive modifications that don't appeal to a broad audience can reduce value.

Mileage plays a significant role in a classic car’s value. Lower mileage usually increases value because it indicates a higher degree of originality, is rarer, and suggests less wear and tear. However, cars with exceptionally low mileage may also have maintenance needs due to lack of use. Whether someone should pay more for a vehicle with lower miles will depend on how they plan on using it, and the vehicle's specific condition.

The value of modified cars differs widely based on the type and quality of modifications. While some modifications can significantly increase value, especially performance enhancements and high-quality custom work, others may not add much or could even detract from the car’s value if they appeal to only a limited audience.
