# 1971-1975 BMW 3.0 Si Sedan The BMW 3.0 Si represents BMW's flagship sports sedan from the early 1970s, featuring a silky 2,985cc inline-six producing around 200 horsepower. Part of the "New Six" (E3) series, this four-door combined refined German engineering with genuine performance credentials. Enthusiasts praise its smooth, rev-happy engine, precise handling, and timeless Marcello Gandini-influenced styling. The 3.0 Si introduced fuel injection to the range, delivering impressive speed for its era—0-60 mph in under 9 seconds. It's famous for establishing BMW's "Ultimate Driving Machine" reputation and serving as a technological showcase. However, rust susceptibility and parts scarcity are notorious concerns. Today, well-preserved examples suit collectors and BMW purists seeking an elegant vintage grand tourer that still drives with surprising competence on modern roads—ideal for weekend rallies rather than daily commuting.
The 1971-1975 BMW 3.0 Si features expensive mechanical fuel injection (requiring specialist knowledge), costly rust repairs on aging unibody construction, and pricey NLA (no longer available) trim parts. Carburetors and suspension components need frequent attention. Insurance is surprisingly reasonable as classic/collector coverage. Parts scarcity is the primary ownership challenge, inflating maintenance costs significantly.
