BMW 325i E30
The BMW E30 325i is the car that cemented BMW's reputation as the maker of the 'Ultimate Driving Machine.' While the M3 grabbed the headlines with its motorsport homologation credentials, it was the 325i that most enthusiasts actually drove — and it was brilliant.
The heart of the 325i was BMW's M20B25 inline-six engine, a 2.5-liter unit producing 168 hp (DIN) in its most common form. The 'iS' version, with its higher compression ratio and sportier cam, produced 170 hp. This engine was silky smooth, rev-happy, and made a glorious sound at full throttle. Paired with the precise Getrag five-speed manual gearbox, it provided an engaging, mechanical driving experience that few modern cars can match.
The E30 chassis was the secret to the car's brilliance. At just 1,220 kg (2,690 lbs), the 325i was light by any standard. The MacPherson strut front and semi-trailing arm rear suspension provided a nearly perfect balance of ride comfort and handling precision. The hydraulic power steering was weighted perfectly, providing the kind of road feel that modern electric systems cannot replicate.
The E30 was available in a remarkable variety of body styles: two-door sedan, four-door sedan, Touring (wagon), convertible, and the Baur TC (targa-top). This versatility meant you could enjoy the E30 experience regardless of your lifestyle needs.
In period, the 325i was the benchmark against which all other compact sports sedans were judged. It outhandled the Audi 80 Quattro, outperformed the Mercedes 190E 2.3, and offered more refinement than the Alfa Romeo 75. Only the E30 M3 and the Mercedes 190E 2.3-16 Cosworth could challenge its dynamic superiority.
Today, clean E30 325i examples are rapidly appreciating as a new generation discovers the magic of this perfectly proportioned, wonderfully balanced driver's car. The iS variant with its sport suspension and limited-slip differential is the most desirable non-M E30, while even standard 325i models offer driving joy that belies their modest specifications.
Rust is the primary concern — inspect floor pans, inner fender wells, rocker panels, jack points, rear shock towers, and the battery tray. The M20 engine is robust but the timing belt MUST be replaced every 60,000 km — failure is catastrophic. Cooling system components age out (water pump, thermostat housing). The E30's electrical system is simple and reliable. iS/is models with limited-slip differential are most desirable. Two-door models command a premium over four-doors. Convertibles are excellent summer cars but check the top mechanism. Service history is important — these cars reward proper maintenance.
Total E30 production exceeded 2.34 million units (all variants, 1982-1994). The 325i was the most popular six-cylinder variant. The 'iS' (325is in US market) added a sport suspension, limited-slip differential, and close-ratio gearbox. The E30 continued in production as the Touring until 1994, overlapping with the E36. South Africa received a unique 333i with a 3.2-liter engine.
