BMW 7 series (E23) (1977-1986)

“BMW’s second attempt at a luxury saloon vehicle”

These days BMW are renowned for their executive saloons with up to the minute technology and fine German engineering at the heart of the company. But back in 1977 the 7 series range was only their second attempt at the luxury saloon market.

The German car manufacturers first attempt was the BMW 2500 which was indeed a fine achievement for BMW however its successor was a far more polished contender. The BMW 7 series (known as the E23 models) was a very sophisticated machine for its time. They were the first BMW vehicles fitted with a system fault indicator, warning the driver should any technical and mechanical problems arise. It also included a complex climate control systems for ultimate driving comfort. On-board computers and an anti-lock braking system (ABS) were also available on the BMW 7 series and later models from 1985 also offered an optional driver’s airbag.

The BMW 7 series (E23) was fitted with a 12-valve type-M30 six-cylinder engines (previously introduced into the E-Series) and 4-/5-speed gearboxes. However in 1983 BMW opted for a facelift where they redesigned the front grille and bumper, added a new spoiler and fitted a newly-developed Motronic 3.4L engine. The suspension was upgraded too.

The first generation 7 series was discontinued in 1986 when the BMW E32 was introduced to the scene.

Big luxury saloons, although not so popular in today’s modern cars are very much a product of the seventies and eighties with BMW’s 7 series truly being ahead of the game. These motoring heavy weights are sadly a rare find now and values are low considering what you get for your money.

The early eighties BMW was like so many cars of the time being prone to rust in the usual places, such as sills, inner wings, rear suspension turrets and sun roof surrounds to name but a few. Most 7 series BMW’s will probably have 15”or 16” alloy wheels these days although early models started with 14”. This isn’t particularly a worry as these big saloons handle better on the bigger wheel.

Check ‘small perishables’ such as water hoses and engine mounts as they don’t best stand the test of time although are easily replaceable. Worn rear sub-frame bushes can affect the handling so take it for a test drive and check those anchors, seized rear brakes can be due to collapsed brake hoses.

As you would expect from BMW the M30 engine is strong and reliable and the 732i was the first to have BMW’s micro-processor controlled Motronic fuel injection. If serviced regularly these bullet proof lumps will give you at least 300,000 miles without needing any major work.

In 1959 BMW was nearing bankruptcy due to a myriad of factors. Smelling blood, Mercedes’ parent company Daimler-Benz mounted a Gordon Gekko style hostile takeover attempt. Collectively BMW then mounted a counter attack, enlisting even the lowest mechanics in the organization’s help in buying back shares. They eventually found the help of a major private investor, whose family still owns a chunk of the company today. This battle of course spurned a major rivalry between the two brands that still exists to this day.

Mark Wilkinson (Managing Partner of Heritage Classic Car Insurance) says

“Car trends change dramatically over time as do car manufactures prime objectives with cost effectiveness being potentially more important than truly meeting the standards once set upon themselves. On the flip side the classic saloons of the late seventies and early eighties are prime examples of prestige car manufacturers at their best.”
