The BMW 3 Series (E46) is a compact executive car that was produced by BMW from 1998 to 2006. It was the fourth generation of the 3 Series, succeeding the E36. The E46 was available in a variety of body styles, including sedan, coupe, convertible, and wagon (called Touring in Europe). The E46 is known for its stylish design, sporty handling, and luxurious interior.

The E46 3 Series was offered with a wide range of engines, including four-cylinder, six-cylinder, and eight-cylinder petrol units, as well as four-cylinder diesel engines. The most popular models were the 323i, 325i, 328i, and 330i, which featured powerful and efficient engines. The E46 M3, a performance-oriented version of the 3 Series, was powered by a high-revving 3.2-liter straight-six engine producing 338 horsepower. The E46 also introduced several technological innovations, such as the iDrive infotainment system and the first generation of BMW's Active Steering system. However, the E46 was not without its flaws. Some owners reported issues with the electrical system, the VANOS system, and the cooling system. Nevertheless, the E46 3 Series remains a popular and highly regarded car, known for its driving dynamics, styling, and overall package.
