MY answer: The 'life' of tuxedo is much shorter than car,it is easily run out of fashion while car does not. And the posibility of people rent a tuxedo instend of buy one is very high, it is because male do not wear tuxedo frequently and it might be not 'nice' if they wear it again in next ceremony or any party. Suppliers have to wash the tuxedo when customer return it to them, thus the cost is high. If any damage on the tuxedo, people will have to buy it, it might not seen to be a problem whereas people have to buy a 20,000 pounds car, people will use it with care. In general, people would rent a car for few days, but for tuxedo it normally would be only one night.
