A certain symmetry

This evening I did well. Two cars, both on Lendal Bridge.

Car 1: 1949, a white hatchback with a 29. South Side.
Car 2: 2328, a 30 of indeterminate colour. North Side.

There is a nice symmetry there I think.

Well, two in one day: Looks like this is getting too easy. I need a challenge. Ok. The next ten sightings will not be posted individually. Instead, they will form a poem. Which will be posted here when I reach #40. There may still be other intermediate posts.
