Nobody sells a car with a fault, especially if the fault is a quick fix. So I would double check that's it is really something small.
The abs and tc lights won't affect the drivability of the car, but since we are having lots of rain and the roads are wet, I'd prefer having abs to be fully functional.
From the sounds of it, seems it's a WBC purchase you are looking at. Maybe post the link. Somebody might know the car or we might be able to help you.
