Sukii desu (was Re: Comer manzanas)

All this talk of "me gusta comer manzanas" etc. prompts me to ask if anyone
knows the "real" meaning of <sukii> in Japanese. AFAIK it's an adjective,
but it's used to show liking much as <gustar> in Spanish:

Kono kuruma wa    sukii desu.
this car    TOPIC ???   is.
=I/he/she/you/we/etc. like this car.

It would stand to reason that the adjective would be something like
"pleasing," but I'm not sure, as I've never seen it explained as an
adjective, outside of this usage. Also, I'm not sure how you specify WHO is
doing the liking... perhaps <ni>?
Anyone know?
