I have a 2000 A160, moon silver metallic finish, [keyed by a mercedes hater]. It's been pretty good and we are the original owners. Lately it runs badly and unevenly and I just stop the car and wait a few minutes, then start again. Seems to reboot the computer. I live in Bondi which is a beautiful surf beach on the east coast of Australia, near Sydney. The salt air is dreadful for any exposed metal and the 1973 280 SE V8 we had rusted to bits hence a new car.
the car had a slight rhthmic sound which doesn't speed up with the engine revs so I am hoping it will go away when the timing chain is replaced and the rest of it [ see my queries and notes about this elsewhere].
I think I'll have to replace this car within 2 years more. I don't think it is up to longevity. cheers! Leee
