Ahh yes Ferrari - might I point out that during their halcyon years (no pun) 2000-2004 with Schumi, it was the engineering team Schumi brought with him from Benetton in 1997 that led the turn around...and it took them nigh on 3 yrs to resurrect Ferrari.
Otherwise there was a slight drought from 1979 (Jody Schekter) to 2000...when Schumi won for the Scuderia again...during this 21 year drought its fair to say that British teams - Mclaren with 9 [1984, 1985, 1986, 1988, 1989, 1990, 1991, 1998, 1999], and Williams with 7 [1980, 1982, 1987, 1992, 1993, 1996, 1997] rather dominated the driver's championships.
For further on the British influence at Ferrari, c.f.:
