Is there any zakaah on cars even if they are numerous?

There are two scenarios with regard to cars. One of them is
when they are used for transportation and errands. There is no zakaah in
this case, as is the case with a camel that is needed, or a donkey and so
on, and as is also the case with furniture. In this case, cars which are
kept because of need and transportation, even if they are numerous, are
exempted from zakaah; the same also applies to cars for hire (taxis). And
the same applies to large transportation vehicles which are kept in order
to use them for transportation; there is no zakaah on them. 

The second scenario is where the cars are for sale, i.e., one
acquires them to sell them and deal in them. In this case zakaah is due on
them as they come under the same heading as other trade goods, and when one
full hijri year has passed since the cash with which they were bought was
acquired, zakaah must be paid on them, or when one full hijri year has
passed since acquiring the car, if he bought it on credit, then he must pay
zakaah on it according to its value. This is what is required. End quote.
