I wonder why we can do whatever we like to our boats and yet many simple modifications on our cars require a mountain of paperwork with the associated Gov fees.
Also changing ownership of a boat costs a mere fraction of the costs for the same value car even though in the West you do the changeover at the same Gov office.
Maybe the car is overlegislated and everyting to do with them is just a cash cow for the Gov.
Personally i think old mates bullbar was very well constructed and if it was fitted with a set of engeneered crash cans it would be as good if not better than some of the commercial offerings.
Common sense needs to prevail But i see absolutly nothing wrong with people moking their own hardware as long as they know what they are doing.
