You sure..?

I just checked Europcar, for a one month rental on a compact (VW Polo or similar) it returned a rate of 1,959.96 chf. (includes 3,000km) but a similar compact from Mobility costs 780.- chf. (includes 1,250km). If you absolutely need 3,000km then the extra 1,750km on the Mobility car will cost an extra 350.-chf (0.20 per km). That's still nearly half of what a normal car rental would want.
