That is a semi-eclectic mix of very clean old and new cars.
Heh. The Miata that is mostly out-of-frame is mine, as is the blue Audi sedan. The minivan is the neighbors, the blue Audi wagon belongs to a friend of mine who was helping (it used to belong to me, but I sold it to him when I got the newer one), and the E39 on the right belongs to another friend who was helping me. The SUV in the driveway and pickup are also neighbor cars.
This is CA, the land of no rust, so cars last a long time!
