sounds liek we have the same spec of car.
mine's a 1991 Rosslyn SA kit build as well, was brought to England in 92.
not surprised the BMW SA guys didn't know anything about your car, BMW Uk, BMW germany and M division and BMW SA can't find any build spec for my car ethier, just that it was built.
sorry to hear about the rubbish workmanship thats happened to your engine previously.
there is at least 1 other SA based E34 M5 owner on this forum BTW. his car is white as well, beginning to wonder if all SA E34 M5's where the same colour and spec' :lol:
