The BMW 3-Series E30 profile

The second generation of the BMW 3-Series is still immensely popular over 30 years after its debut. Here’s what to look out for when buying a BMW E30.

The BMW E30 was introduced in November 1982 as the successor to the E21, which was built from 1975 to 1983. The German automotive designer Claus Luthe was tasked with continuing the BMW 3-Series bloodline started by his predecessor Paul Bracq. While retaining the spirit of the founding E21, the E30 was offered in significantly more variants than just a two-door car – a four-door model was available from September 1983, followed in 1985 by a convertible. However, the most iconic derivative has to be the legendary E30 M3.

The BMW E30 model range

The BMW E30 was available in a variety of body styles throughout its production. After the introduction of the two- and four-door sedan, the Baur Topcabriolet followed in February 1983 along with a full convertible in 1985.

The new BMW E30 M3 could be had as a sedan and convertible; both versions are in particularly high demand today and change hands for a premium. In July 1987 an estate variant of the E30 was introduced, named “Touring”, as is the BMW tradition.

During the production from 1982 to 1994, about 2.3 million examples of the BMW E30 were produced. The car was offered with a number of engines, the performance ranging from 75 (316) to 238 (M3) bhp. Two diesel engines were also available, serving-up 86 or 115bhp.

BMW E30 Bodywork

As with most vehicles of this period, rust is the enemy of the day. When buying an E30, special attention should be paid to door edges, bonnet edges and the boot. It is well documented that E30 sunroofs are also prone to rust, with repairs being very time-consuming and expensive. Since the front panels are vulnerable to stone chipping, rust spots are often found here, so take care to inspect these areas. Also take a look at the mirrors, which are a known weak point of the E30.

When looking over an E30, you should also inspect the rear lights, the rubber seals of which often weaken over time and allow water in. A close look inside the boot is strongly recommended as any rust is usually hidden by the carpet. Issues with window frames, wheelarches, strut bars, tailgate hinges and the rear window wipers aren’t specific to the E30, but are still worth checking.

Engine and mechanicals of the BMW E30

If the BMW E30 in question hasn’t received the greatest maintenance over the years, you can probably still have many miles of fun due to its durable build. That said, the timing belts of both four- and six-cylinder engines should be replaced regularly; if they break, there is a risk of serious engine damage.

If the six-cylinder has been driven too hard, cracks may have formed in the cylinder head – this can be identified from the mixing of engine oil in the coolant (look for a white emulsion on the inside of the oil filler cap). Known problems with E30 engines include defective water pumps, viscous fans, timing chains, camshafts, rocker arms, ignition distributors, injection valves, bucket tappets, duplex timing chains, cylinder heads, fuel pressure regulators, and connecting rod bearings. That might be a sizeable list, but many of these are due to simple wear and tear. A good test drive should reveal most issues.

The cost of repairs or replacements are inline with other comparable vehicles of the era, with some easily carried out with your own set of spanners. Spare parts are relatively easy to come by for the E30. Components are usually available from specialist dealers and even car recyclers.

BMW E30 Conclusion

Buying an E30 BMW affords you a classic that you can truly use everyday. Examples of the Cabriolet and M3 versions are particularly sought after, as is the more practical Touring model. Despite the large numbers produced, well-preserved examples are not easy to find due to rust or extensive modification.

With so many engines and derivatives of the E30, it is worth investing some time researching each model’s nuances. It will be worth it in the end!
