The 70k service isn't a big one, little more than an oil change really - assuming you are on time and distance.
T&D services
10k - oil change
20k - inspection service
30k - oil change
40k - the big one which is a more comprehensive inspection service (forget what its called) including sparkplugs

and the pattern repeats. brake fluid is due every 2 years, air filter at 60k and if not already done I would be thinking about getting the cam belt changed.
So it shouldn't be too expensive really....
My 40k (same as 80k) cost just under £295 not including the brake fluid (£49) and a/c service (£75).
Not sure how long life differs from this.
