I was followed for a while up Rockville Pike by a silver or grey blobeye WRX wagon this evening. I tried waving but I think it was missed in the dark and traffic.
Didn't get a great look but I saw dark rims, a large but not excessive exhaust, and I could hear your turbo spool clearly. Nice ride, and nice blonde in the passenger seat.
I was the 06 grey WRX sedan.
