It's made by RCL International.
The parts label mentions
DURT FORMULA
4WDs INCIDENT
Durt is not my typo; theirs

I found only one reference on the web to it: an old post on the rcca site saying the company died 14 years before. (And that post was from 2002)
If anyone got pics or a manual I could check how much stock they have and what's missing to build a car.
(It looked as if there were 2 different plastic chassis types, so maybe they had more than one model.
Here're pics of the last set of tires they had (till I bought it). One with the label, and one with a closeup of the imaginative tread

Maybe it rings a bell? Could be I was looking at a clone of a better-known company...
