1987 E30 owner - even after getting the mold out during a restore, and in spite of a crack in the bolstering, the E30 sport seats are the _second_ most comfortable I've had the pleasure of owning. The seats in these old cars definitely have something up on modern leather seats, even its 27-years-older brother (4-series) that I drive daily.

The champion in that department, though, was the 1986 Volvo 740 that I briefly owned. Those seats were perfect in nearly every way.
