It's a scare tactic. Unless they have some kind of dealership cover when the warranty expires. As long as the mechanic uses genuine parts, the manufacturer warranty will still be covered. (Not too sure, but they might also have to be MTA approved, which Ultratune are from memory). I was taking it to the dealership for the first 40,000 coz I wanted to keep the service book 'clean' and get the out of warranty cover they provided after the manufacturer warranty ran out, but then I got sick of them ripping me off so I get my partner's father to service it for me. :) A whole lot cheaper and more reliable. I used to take it to the dealership every 10,000 and it'd cost about $150 - $250 (~$300 for the 40,000km service and an extra $150 for them to rotate the tires for me.... give me a break) Now the father-in-law services the 5000km for $30 and the 10,000km's for $70.
