my first service was free... after that it's every 5000km. This is how my dealer works; they do a minor service every 5000km and a major every 10000km. So 5000km it's about $120 (took ~2 hours), then at 10000km they do a more thorough check on everything (took about 3-4 hours) and cost $220. Then repeats again @ 15000 then 20000km etc...
Is this the usual service cost and what is the cost for extended warranty ?
