2007 S600, 2007 Chrysler 300 SRT8, 2000 C5 Corvette, and 2017 Mustang GT, and just got a 2023 300C
So I did a quick internet search and believe it or not Pep Boys has two locations around here!!!! Just checked their web site for spark plugs for my S600 using their search tool. According to their site, platinum is $5.99 ea. and iridium is $10.99 ea.

RockAuto is clearly a better deal.

Hello all,
Haven't been able to find a match for my particular situation in the forums. I have an '08 S550 4MATIC, 180,000kms.
There's a strange vibration / buzzing noise coming from the front of the car that's especially noticeable when I drive slow, seems to be from the left side. Vibration can be felt in the steering wheel.
Doesn't matter the position of the steering wheel and it only happens when the car is moving (forward or reverse). As soon as I stop, it stops. Car can be cold or warm.
It's there when braking, or if the car is coasting in neutral. Sometimes there's a weird click and then it stops for a few seconds.
I've taken off both front wheels to see if there's something dragging on the wheels & brakes but everything looks fine. Pads were replaced in the last year. CV boots are all in good shape.
I thought maybe steering related, but there's no noise when rotating the steering wheel when stopped (I topped up power steering fluid anyway, no dice). Steering wheel feels normal, doesn't pull.
Wheel bearings? But then why would it sound fine 20% of the time?
Scratching my head. Any thoughts?

Without hearing it, I am just guessing; but I would bet you a donut your problem is bad motor mounts. Easy to check. Open the hood (bonnet), put it in drive, hold the brake with one foot and slowly accelerate with the other foot. If the engine shifts position or jumps, put the car on a lift (ramp) and check the engine mounts for clearance. I am guessing the sound and vibration you hear and feel is the engine collapsed on the motor mount and touching the frame. Mercedes says the engine mounts are a maintenance item. They are typically oil filled and as they age, the oil seeps collapsing the mount. And if you replace the engine mounts, while you are there, check the transmission mounts. They all have about the same useful life. Good luck and keep us posted.
