Alpina B3 Touring
Why 7.0: No DougScore, but huge enthusiast pull: forbidden-ish wagon body, Alpina calibration, everyday miles and less track cosplay than an M3.

Sound
Alpina's exhaust gives the S58 a creamy six-cylinder rumble, more mature than the harder tone BMW's own M cars use. But discretion is the point: the valves barely open, the filters do the rest, and 7,000 rpm passes without event. Tasteful and quiet by design.

Median asking price, good condition · €75k (2020) → €57k (2026), trending down · illustrative data
Child seats · ISOFIX
Two outer rear ISOFIX positions on the donor G21 Touring's bench, middle belt-only — the estate body doesn't change the seat hardware from the G20 saloon.
Alpina-tuned G21 3-Series Touring — no front-passenger ISOFIX, same as the donor platform.
Donor BMW 3-Series Touring (G21) ISOFIX pattern — mainstream family-estate segment norm, EU ISOFIX mandate; no Alpina-specific document located (owner-community sourced, not manufacturer documentation)
The long version
The B3 Touring is the Alpina sweet spot: enough performance to humble old supercars, enough compliance to cross countries, and enough wagon utility to make the purchase feel almost rational. It is not a track car, and that is the point. Owners buy them because the car solves a real life while still feeling like a secret handshake. That earns a high score even without Doug coverage: it spreads the axis better than another limited supercar would.
