Before you ordered plugs,
did you check to see if they were getting ANY juice themselves? Problem easily could be upstream from the plugs.
Now, if you just wanted new plugs for the sake of new plugs and the old ones were shot, that is different obviously.
Nice car. I like it..... I am partial to Mercedes styling and like the C class, especially the 300 4 matic
Unfortunately, I am not interested in the cost of maintenance on these vehicles or the parts.
So I drive a 2015 Hyundai Sonata Sport trimmed out. Very nice ride and everything we need to be comfortable, quiet, and enjoy a smooth ride and a long warranty.
IF it performs like my last vehicle, it should last for a long time before needing replaced.....
That is my goal anyway....
