I got mine done today,
My car only has 19500KM on it, 2 YO this month..
My dealer quoted all up $350 and I get a small 10% disc and total was 320.
The other dealer closer to me quoted about $420.
The service is about 200-210 itself but regardless of KM the brake bleed , flush out and new fluid plus the coolant flush and refill make up the rest and are required every 24 mo.
The thing to remember is that Mitsu has to do your service once per yr to keep your roadside assistance for the 5 yrs of the warranty.
They use the auto clubs to provide this in each state. So if I get the service done by a non dealer or a mechanic mate for 200+ I then have to pay the RACWA roadside fee which is over $100 anyway so it comes out basically even over the 1 yr period.
After 3 yrs they have to do an inspection also to verify your warranty out to 5yrs (its in the book)
All these dealers charge too much and as u can see from my figures some more than others so it pays to call around.
