In Tae Kim's grammar guide, it tell you that question word can be appended with か、も、でも to mean different things(誰か someone, 誰も everyone, 誰でも anyone).
Can the same be carried over to counters? For example, is the following valid?
幾つかの季節 (I know this one is valid, I've seen it being used, "some seasons")
何台かの車 (Can I use it like this?, "some cars")
何台の車か (Or maybe like this?, "some cars")
