RE: Which manufacturer would you like to see in NASCAR?

On the safety part.
For all the roll cages and such, it takes a harness wrapped around the drivers head to prevent his neck from snapping to save lives.
All other racing has roll cages they can put into existing cars. NASCAR could do the same. Verify that the cage meets standards and go on from there.
Most manufactured cars probably couldn't sustain 160+ MPH races, let alone top 200 MPH.
