2005 BMW 325xi
The 2005 BMW 325xi is an all-wheel-drive variant of the E46 3-Series, known for its balanced handling, refined driving experience, and relatively compact size. The 325xi comes equipped with a 2.5-liter inline-six engine (M54B25) producing 184 horsepower and 175 lb-ft of torque. Other engines available in the E46 3-Series included the 3.0-liter inline-six (M54B30) in the 330xi, and a smaller 2.0-liter inline-four in other markets. Transmission options for the 325xi included a 5-speed manual and a 5-speed automatic. Owners often praise the 325xi for its sporty driving dynamics, solid build quality (for its time), and classic BMW styling. Common complaints revolve around the high cost of maintenance and repairs, as well as the age-related issues that plague many older European vehicles.

Summary
The 2005 BMW 325xi, while a well-regarded vehicle, is prone to several age-related issues. Engine oil leaks (valve cover and oil filter housing gaskets) and cooling system failures are common, and can lead to more serious problems if left unattended. Suspension components, particularly control arm bushings and strut mounts, also tend to wear out. Electrical issues such as window regulator failure and instrument cluster pixel loss are also frequent complaints. The costs of these repairs can vary significantly, but are often higher than those of domestic vehicles. Transmission issues, especially in the automatic, can be particularly expensive. While some issues are relatively minor and inexpensive to address, others can require significant investment to resolve.
