I do believe the wheelbase is factory length. The front doors are longer than a four door giving the illusion that it is shorter.
Anybody have some info on the model kit? I've never seen one but would really like to add it to my collection.
Sure it looks better: this is official GM creation! They seriously considered to put it in production but the whole B-body line was about to be axed at that time... Notice it have a shorter wheelbase.
