Had them a few years ago on different cars, then grew up and out of them -.- pretty much useless, I never really noticed much difference with them...
its never going to be a silent drive.. no matter what you use, want it quiet? close the window -.-
its actually cheaper then you think.... did a little looking around the site, there are two UK Companys that use the pasti dip
Full Car £250 - London
Starting from £500 also in London
I don't think that's right.. Can't you just book it without being told to by a the police?
What if a new driver wants to do it?
As for speeding, its a touchy story, different between 5mph is life of death for someone.. speed limits are there for a reason, no matter what time of day, so many...
