There was a nissan/infiniti event on the campus of Cal State Fullerton in Fullerton, CA this past Sunday.
Mostly it was a lot of 350,370z's and G35/G37 coupes. I didn't see any altimas or maximas and the car show was rather small. I've been to larger car shows such as the Fabulous Fords Forever in Anaheim, CA
