It almost hurts to see a beetle being wasted like this primarily because of the shrinking number of good usable / restorable cars in Pakistan but maybe the owner has a plan. The lines that he has chosen are not ordinary so lets see what the finished product is like (if it ever gets finished)
I like your term Maddification but would refrain from using the other phrases. We do not know what was the condition of the car prior to the ...maddification. Maybe the car was already on the chopping block and is better off this way.
... and remember, .....to each his own!
