'99 C280 with 65000 miles
I'm the third owner with only partial records from the first two owners. There is no record of the spark plugs being changed so I don't know if they were or not. Is it possible to pull one of them and determing if it is original, i.e. excessive gap, erosion, color? These go for 8-9 dollars a pop so I'm hoping they have already been replaced. The car was manufactured in August, 1998, so an original plug would be over 7 years old. Couldn't find an answer to this in the archives.
Thanks for any help, Dan
