I don't know why, but some of the car models won't come up when seaching?
For example this one: https://clevrcar.dk/vehicle/2010-audi-r8-4-2-quattro-921/
Audi R8, but there is no "R8" model in the dropdown - so it can't be found.
Same problem when choosing "Land Rover" as brand. I've added 12 land rovers but it says that there are no cars that match the brand.
