hmmmm i guess you car wants its periodic attention from a mechanic, who
will check all kind of stuff and the car will feel and run great again.

needs a service

The idea of the spanner is to indicate that a service is due.   It should be
reset after each service and then counts down the miles.

I had that one... it's a 80K service, ?450 to me, cambelts and stuff. :o(
