Not sure how it is down under, but back home stateside a lot of stuff is done "by the book". If you brought in your bike one day and didn't get back until 6 days later just because three of those days were spent trying to find parts, reading the manual (they make them in english, right?) and scrathing their heads figuring out how they work, not to mention storage fees, make sure you're not gtting the wool pulled over your eyes dude.
Make sure they come clean. Students need all the cash they can hang onto. I know that all too well.
