I've just bought a '92 Celcior, & it is the absolute dogs! I can't compare it too an LS 400, because i've never been in one. But i have been in a friends GS 300, & it is alot better. Having said that i do have the usual problems? :- everythings in japanise, & k/ph! I don't know what it would cost too convert it to UK spec, but i suspect it would be brewsters! :zee:
