I have some kind of feeling that Kreivi was more than once "late entry"
.
It would be nice to know about his M1's engine. Some times it was printed as M1 Turbo. I remember that once they had kind of BMW Motorsport "parade" between the race starts in Kemora. Wiik in 320, Kreivi with M1 and Bächi with Sauber M1? It could be the very same race that I have photos, because I can just remember (I was about 8-9 years old..) that both of M1 were almost all white. Other had Turtle Wax as sponsor. At the time 320 Turbo seemed to very old tech. Funny how it took to till 88-89 to Bächi get his M1 suited to Kemora and Nicke seemed to be almost every time faster with 320.. Of course Nicke had real advantage as Kemora is his home circuit.
There was once rumours that Kreivi's garage was burn (86-88) and all the equipment with (M1 also) it.
