6t9REP = repairable writeoff shell was used.
6t9REB = a totally written off vehicle shell was used.
my evo 5 is registered as a 6t9rep and my old evo 1 was registered as a 6t9reb.
can be registered in w.a, vic, qld.
however, syd can also be registered if the car has been registered for a long time and has been through a recall and been given a vic roads certification to say the car is all clear. Check RTA website.
S.A im not sure of.
its not just rebirthed cars that get recalled... all import vehicles do.
cars under the rep/reb plates were registered either one of 2 ways...
1. that an evo was bought and everything was swapped into the lancer shell.
2. that an evo was bought and the vin was swapped over. (so the evo keeps its genuine shell.
hope that clarifies things.
