Not as rare as you think, perhaps? I'm always seeing ancient iron rolling down Bothell Way, especially around the Lake Forest Park/Kenmore area. Over toward Bellevue it's all BMW's and Lexus' (Lexii? Lexum? Luxojunk?). I don't often go out as far as Issaquah; my favorite boneyard is in Woodinville, so my our paths may never cross.
There's a guy I see nearly every day heading the opposite way on Juanita drive in his 50-something Frod p/u. I usually wave (with all my fingers

), just to be sociable.
