mr2 turbo with HG failure - dont!
can pick them up for cheaper than that these days and they dont have that many problems! GT4's are going cheap and are pretty nice drives.
prelude - watch for dreaded rot around the windscreen, boot under the number place and also back arches are a killer on them as well. roof seals around sunroof are prone to leaking as well after a while... but overall mechanically theyre sweet as a nut if looked after. 2.2 VTEC is the only one i'd even think about going for as the 2.0 is quick but not that quick.
celica GT - if its an early model look out for sills, doors at bottom, and again rear arches being rusted... engines are getting a bit rough on them as well on the earlier import models if not serviced regularly.
