Hours of sitting next to a track will teach you a thing or two about the cars running on it.  The “Rusty Trombone” Passat is named not just amusingly but accurately as well: the slick side-trunk-exit exhaust produces a tone as mellifluous as that produced by the brass horn on the car’s roof.
The wood-paneled Ford station wagon has made a respectable showing, even though it didn’t quite start on time.  Something like half the cars are still running the course, some sporadically—our favorite backwards truck is still making laps every now and again—and some consistently, believe it or not.  Two BMW E30s were leading for most of the morning, but it’s been a while, and there’s still a good hour to go.
