Ahahahaha, I know the Steve you speak of…cheeky guy, great fun too! But then again we went to school together so my opinion doesn’t count.

what tribe was he and where did he live?

If it is the one you speak of, he drove a 124 Mercedes and lived in Muthaiga.
I could be wrong but your description fits.
