Racing Sports Cars is a truly wonderful resource and rabbit hole to get lost in, a great website documenting so much history in one place. It's fun to just browse the random photo and see what weird and wonderful cars and events I fall over. And occasionally, something will catch my eye. A little thing I've recently taken note of is any car that's carrying significant damage, because there's few enough to be rare and notable when found, but not so rare that they're frustrating to find.
The pedant in me wanted to lay down some strict rules at first, like the car has to DNF, but that quickly excludes cars I wanted to include because I like the image.
