This is really weird and really difficult...
The man I am looking for , his name is Arthur...he must be aged around 50 in 2008, he was in Johannesburg in 1977 and 1978.
He drove or had access to a jaguar, probably an e Type.
He lived in Hillbrow, and made trips to Durban.
He could have been friends with someone called Grant, whose surname is probably Ramage.
He could have been friends with the Darby-Lewis', but of this I am not sure.
