Long ago a reknown Japanese company examined, measured, photographed and thoroughly studied a 1:1 example of a certain US armored fighting vehicle. Said kit was highly anticipated, and considered state of the art when released 30+ years ago. That was until someone who had quite a bit of experience with the real tank noticed it sat way too high. Seems our esteemed collegues from Japan examined a tank from which the engine was removed. No one noticed that at the time, therefore no one caught the fact the suspension was "unloaded". The kit in question did not have an interior nor did it have an engine so these weren't part of the initia lexam.
My point, things are only as good as the engineers who make them.
