At what point did you start lubrication on the top? I am picking up a 2012 328i convertible at the end of the week (It's currently at the port and waiting for transport to the dealer), or since it will be under warranty is this something to even consider doing?
It's officially my husbands car, but just like the 5er we will both share it.
