Unfortunatelly the MOT rules in my country are very strict: you can't touch rims& tires(except the dimensions admited by the producer at the time when the car was launched), brakes, head lamps. I tryied this year to add some LED Daylight driving lights, in order to make the car visible without using the whole set of service lights, but I found it forbiden and even subject of the cancellation of the car's registration !
I will try now a device using the high beam of the car....seems they will not notice that is an aftermarket fitting.....
There are also problems when changing the exhaust , if it's laud.....
The only field without restrictions is the interior......
So I like so much the accuracy of Barone's work , but I can't touch....too much.
