In the past year I have only encountered one M850i convertible on the streets. Ironically given the sighting has been on my commute to work I found out that the owner works at my company but is based out of corporate building about a 1/4 mile from mine. Truth be told the discovery was made as I made my way through that location's parking lot into the building for a meeting that was held there. Needless to say I did a bit of gawking during the discovery.
Wind the clock forward to this week in which I once again encountered the M850i convertible on my drive to work. The difference being is that for the first time I was in my M850i coupe and obviously there was instant recognition on his part as I'm sure he was surprised to see another M850i/M8 on the road.
