My regency experience is crap as most of the others have been. My car got defected for an exhaust too loud. Got a stock system put back on to pass regency. Went in and got defected for anotehr 10 things. These included worn rear diff bushes, split brake lines, new calipers needed, twisted seatbelt, exhaust still too loud.
Went to kents engineering in adelaide and had it all inspected. Brake lines were perfect as were the rear diff bushings. These guys are pros and searched the brake lines for 30 mins and still couldnt find anything wrong with them yet regencuy insisted they were changed so i did. The twisted seatbelt is just a joke i think. took like 10 seconds to untwist it. A stock exhaust too loud on a NA r31??? so i had a second muffler fitted.
went back but this time my dad tok the car through. they didnt even put it on the hoists and it passed. he drove in grabbed the forms and drove out. It costed me a grand nearly after all the hassles and there was nothing wrong with my car.
also the girl who used to work at regency is on the pulsar forums udner regency_chick
