The BMW 3 Series (E30) is a compact executive car that was produced by BMW between 1982 and 1994. The 325i and 325is were two of the most popular variants, offered from 1984 to 1990. These models were powered by a 2.5-liter naturally aspirated inline-six engine (M20 engine family) that delivered impressive performance for its time. The 325i produced 170 horsepower, while the 325is, with its more aggressive camshaft profile and other performance enhancements, boasted 192 horsepower. Both models came standard with a five-speed manual transmission, with a four-speed automatic transmission offered as an option. The 325i provided a comfortable and refined driving experience, while the 325is offered a sportier and more engaging drive, particularly with its standard sport suspension and larger wheels. The E30 325i and 325is were praised for their handling, ride quality, and overall driving experience. The iconic BMW handling characteristics were present, thanks to the car's well-balanced chassis and precise steering. The interiors were well-appointed and offered a premium feel, with comfortable seats and a well-laid-out dashboard. However, like many cars of its era, the E30 was not without its drawbacks. Reliability could be an issue, particularly with the engine's cooling system and electrical components. The 325is, with its sporty design cues and performance, became a popular choice among enthusiasts and has since gained a strong following as a classic sports sedan. Its enduring appeal lies in its combination of timeless styling, athletic driving dynamics, and the iconic character of the inline-six engine.
