Mesh quality check for VWT

In the introductory video for VWT , it was specified that even if the mesh quality is bad enough still VWT gives quite a reliable solution for the model we are trying to simulate. But it won't be absolute

I want to ask that which parameters in the quality check of mesh do we have to take care of to get the best simulations of a race car(identical to real life)?
