i've got assorted cars roadworthied for quite a few people but they are not Dodgy. They treat me with respect since i bring them business from other people. They are fair but concentrate on all the essentials.
A word of mention but, i had my car Roadworthied 3 Years ago but the list of improvements, mods and just little things that i have fixed is Huge. Our Zeds are driven a certain way that demands a level of saftey. Would you really want to go for a Great Ocean Road cruise and put your pride and joy into a barrier because of a faulty part?
It can be daunting to take to a Roadworthy but it is just a list, when you start knocking things over on that list it's a good feeling.
