Depends what parts you need really,
All of the JZX90/100/110 are IS200 underneath. So arms, Diff, Shafts etc are easy to get.
cefiro is just S13 underneath, so same as above.
The Chaser shouldn't be too bad for body panels as there are lots in the UK and Ireland but the main issue will be things like lights, glass and things like that.
Shouldn't let it put you off however, just got to be willing to suck up the bill if it goes wrong.
