Well, it's kind of hard to blame anything or anyone but myself for the panic and grief that I just put myself thru..... ...
I have in my hands, as I type, the maintenance booklet for the car.
Ahem, .... every 15000mi (24000km) Check spark plugs. Replace if necessary.
every 30000mi (48000km) Replace spark plugs.
Considering that there was a minimum of 60000km on the plugs, it's no wonder the car acted up and didn't want to run.
My face is red.
Again thanx, Gilly.
A mercedes is an inanimate object and therefore must respond to logic and reason.
