Carpet for the boot, I always have rolls of carpet round me get um from skips or carpet lads working stop ask um for off cuts old carpet there replacing ect, put it in all feet weels and boot soon as wet or dirty smelly throw away put fresh ones down. Set covers or throws easily washed or put through the washing.
Snap top container on the back seats one for game one wet clothes ect again easy cleanable when dirty or smelly.
Plenty of airfreshener and on dry days air the car all windows down and boat left open.....
But still I drive in a car that smell of wet dogs and ferrets
