Look what I've found. I am not sure if it's been posted yet. Apparently a German guy does Oldtimer Rally Racing with his beautiful Carlos Sainz Group A Replica Celica. Check it out!

Front lip definitely says ST162, but when Googling Dietmar Weiss, a GT4 is listed.
Not just the front lip, it doesn't have any ST165 body parts (bumper, skirt or side panel). Anyways, very nice project!
