if you are talking service parts - yes.
correct. though you may get lucky and find some bits of it ex MLB.
plenty of the wound back. its only 4 bolts , 3 plugs and its off and swapped out. importers do it , yards do it individuals do it. if there are any japanese service stickers in the doors sills or on the side of the dash have a look at those. clocking seems to be more common on the 2 door ones.
same as every other car. if its taken care of then it will last a while.
usually. they suffer cam sensor problems , various electrical faults and the like. windows and locks are the worst two unless its been fiddled with then its a pain in the ass to work with. ( I fix these cars for a living.) if it has CVT-8 any where on it - AVOID IT. they are great when they work and will write teh car off when they break.
