As far as I understand the Totalmobil
insurance covers your car at least until the very first service. If every other service is done
by an "authorized service partner
" it is extended indefinitely.
Question: Your garage is not an "authorized service partner" of AMAG?
The Totalmobil insurance includes a CHF 500 cover
for a rental car in case of a break down/accident/loss.
Other insurance companies also offer a similar brake down cover for a certain fee. approx CHF 80 -100 / year. CHF 500 or 3 days seems to be a standard number.
If you drove at least five years w/o any additional cover you are even.
If you saved more than CHF 500 (money, time, convenience, etc) by using your local garage you are even too.
