V8 swapped Miata would be funny.
Though I'd pick something more aesthetically pleasing to me than a Miata, but to each their own right?
I really don't like the looks of the car; of them, the NC is the best. Actually, I don't even really like convertibles.
I'm picking the Miata to muse over a V8 swap because a) the car is regarded as one of the finest handling and driving cars around, b) the car is cheap to purchase, own, maintain, and modify, and c) it is one of a rather short list of cars with enough space to fit in a V8.
