When we make a vehicle for Blockland which is based on a real car, we try to redesign it and adapt it for Blockland's style and proportions, the negative side of only following a blueprint is that, often times both of these things won't be there, and the car will often turn into a low poly version of the real car, instead of a Blockland counterpart, thus mean a lot of round and complex shapes are there, and some areas have more details than it should, Blockland vehicles are simpler than that and the Blockhead size can affect the design, so changes must be made, but not much so it will stay recognizable as the real car.
