Dog crates for the boot - recommendations

[Hauntedmaison]

Looking for recommendations for a crate for the boot. Ideally crash tested and nothing that’s rattly
Thank you

I just bought one on eBay. It fits tight across, front and back slightly tapered to the angle of the hatchback door. It has two doors side-hinged one side and one big door the other, top -hinged. It came with a divider so puppy was only in half to start with.
