This is something I only discovered recently, but it is well worth checking out if you have a Saturday morning free. Check out
www.exoticsrtc.com They meet every Saturday morning (weather dependent) at the Desert Fire parking lot of Redmond Town Center. There are some seriously nice and rare cars that show up at each event, with a strong showing of Lamborghinis (everything from a 1986 Countach to several 2010 Murcielago LP 670-4v's), many old and late model Ferraris, Porsches, Alfas, etc... Last time there was a Alfa Romeo 8C Competizione as well as 2 Carrera GTs... I don't know of any other event in the Northwest where you can see this much exotic machinery on a regular basis, and chat with the owners (again, the show doesn't happen if the weather is forecasting rain).
