Replica Ferrari 250 GT Spyder California - was the movie copy good enough?

I like car movies. Many you may remember "Ferris Bueller's Day off", when the two youngsters tried to turn back the mileage clock when the car fell down and left the house through the back window. Of course we wouldn't have wanted to destroy an original Ferrari 250 GT California Spyder for this scene, right?
But, if you look at the replica car today with its Ford 289ci/4.7
V8, is it really good enough? The shape seems to be okay, if we compare it with an original car. But the detailing sort of got horrible. Light covers, windscreen and stuff like this seems to be quite wrong.
I am sure most people watching the movie didn't notice. So, we saved a great car and the movie hopefully made its budget in revenues.
But I rather don't have a 250 GT than the fake one.
