Yesterday I saw:
EB 520 right by the 405 interchange - Brand new E92 335i, black, temp tags. Around 2:00 PM
Issaquah, in the parking lot near Fred Meyer - SG E90 335i (parked, far NW corner near other stores). Around 5:00 PM
SE 8th in Bellevue near the 405 On-Ramp - Red E46 M3 Cabrio, turning westbound onto SE 8th from 118th Ave SE. Around 7:45 PM
Also spotted a handful of various 325s, 330s and 328s throughout the day. I wasn't driving my E90 335i until about 7:00 PM last night, so maybe only the M3 might have spotted me.....
