OMgosh, #4 is an ALPINA airbag wheel ?. Looks real chunky and very different.
I would say #3 is the nicest of the non-airbag wheels. For 94-95 models of M50 motor, the E36 M 3-spoke airbag wheel is rather nice.
I have a four spoke E46 330i wheel retro-fitted to my 94 stock airbag. Its definitely smaller. Maybe 330mm diameter compared to the stock "bus" wheel.
