It looks like a very nice kit Ray !
Those solid headlight covers are correct for a race ready Cheetah , but I agree with you that clear ones would look much better . Maybe you can find a clear package with the proper curvature to it or maybe a water bottle ?
The grille opening is just that . . . it's open ! I was thinking of putting a black screen on the inside or maybe some driving lights set inside the opening .
And it won't look right without some more meat on those wheels ! The ones included are probably the right letter size tire but in scale they look too small !
I haven't even started my Cheetah yet , in fact you'll be done with yours before I do ! Can't wait to see it !
