I spotted three ZHPs in the same parking structure at my gym today. One was my father's 2006 330Ci TiAg coupe. Another was an Imola on Black leather sedan with a Steptronic transmission. I parked next to it (end spot, ftw). The third was a Silver Gray sedan on Black leather with a manual transmission. I didn't have anything to write on when I came in, but when I left the gym I had written two notes complimenting them on their cars and they should take a look at the Mafia. Sadly, the Imola sedan had left, but I left a note on the Silver Gray sedan. As I was leaving the lot I spotted the driver and recognized him as an older gentleman (mid to late 50s probably) that I had seen in the gym who was deadlifting 295 lbs. It was cool that there were four ZHPs in a single lot (including mine), plus the Alpine White sedan I see parked outside the lot frequently, with a potential sixth Sparkling Graphite coupe that I see parked at my gym every so often.
