I was just browsing the Car Parts & Spares category,
& found that they are all lumped in together.

Surely it would make more sense to split this section into manufacturers?

Cars & Vehicles/Car Parts & Spares/ BMW
Cars & Vehicles/Car Parts & Spares/ Ford
Cars & Vehicles/Car Parts & Spares/ Peugeot
Cars & Vehicles/Car Parts & Spares/ Vauxhall
ect
with a catch all category as well
Cars & Vehicles/Car Parts & Spares/ Universal
for things like wipers & bulbs that don't have to be make specific

Also maybe add Car Modding as a sub category
split again by manufacturer

Cars & Vehicles/Car Modding/ Ford

OR
add Car Modding to Accessories

Cars & Vehicles/Accessories & Modding/Ford
Cars & Vehicles/Accessories & Modding/Vauxhall
ect.

Then maybe there wouldn't be modding & parts in the
Cars & Vehicles/Cars & Passenger Vehicles/by Manufacturer
sections.
