too many to name... im always impressed at datsun day how great some of the SHOW cars are there... plus everyones tastes are different.
I think to be considered it has to still be a datsun body, and datsun/nissan motor which doesnt go with what ive done with my ute (not that i would consider it the best by far), but its an important criteria if your considering a car to be the best of a particular brand.
