I think it will look more scale on the back, (i would hate to have to haul my spare off the roof in real life) but I don't know which balance point is better. On the back she's going to want to wheelie over obstacles and flip back. On the top she might rock over sideways.
I just got a spare...
When I was single, the extra bedroom in my apartment, was wall to wall Ho scale slot car track. :) I miss those days sometimes, but I have more hobbies, than I do time to enjoy them, so I have to be selective.
I am jealous none the less! :thumbs-up:
