I found some literature in a black 91 M5 I bought last year. Figured it'd be interesting to you E34 fans.

1. Car and Driver - July 1991 (1991 M5)
2. Road and Track May 1993 (Dinan 535i turbo, Dinan Stroker M5)
3. Roundel - May 1996 (Dinan Engineering, 540i turbo race car)
4. Car and Driver - July 1988 (Dinan turbo M6)
5. Roundel - January 1994
6. European Car - April 1994 (Dinan E30 M3)
