Repair work not disclosed when buying car

I bought a G20 M340i @BmwVereeniging in 2023 November and they did not disclose to me that it was repaired due to possible accident damage, I found out now when I’m trying to trade the car in and I can’t get book value for the car because of the report on the car.

One dealership requested the repair report so that they can revise the purchase offer for me, I called BMW Vereeniging and they told me they don’t have the report, I went through the effort of finding the repair centre myself and the repair centre also can’t give me the repair report and invoice because of POPIA as the car didn’t belong to me when it was fixed.

Now I’m stuck with a car that’s undervalued and is running out of motor plan and I can’t trade in for a newer car.

BMW South Africa said they can’t help with the issue
