The 3.0i Z3 finished in the new Sterling Grey with white chameleon leather attacted a lot of attention. I predicted Sterling Grey would be lighter than Steel Grey (on the basis that Titanium Silver is lighter than Arctic Silver) and it appears under the lights that this is the case, but I wait for a natural light shot to be convinced.
The console is in turned aluminium, rather like that of the Morgan Aero 8. Wonder where BMW got the idea from?
