I could seriously see her going to JR Motorsports and driving the 88. Shes sponsered by Go Daddy so it MIGHT work. Then where does she go. Would Junior consider bringing her up with his own team if she starts driving for him.
Hopefully she sticks to Indy. By the time she would be ready to go to Cup (probably never would be anyway in my opinion), she'd be getting older and her marketability would fade as her looks did. There is no denying that companies see her looks as more marketable than her talent, however dumb it may be.
If racing was completely based upon a driver's talent landing them a ride, Dick Trickle would have gotten a quality Cup ride and won some races.
