I request a referral to a good MBZ shop in Walnut Creek CA for a customer buying this vehicle. So she can have a prepurchase performed.

Hello Mark, Seems some of the 274/278 engines look like this below 100K on the clock. Is it spark timing, poor fuel and the motor doesn't adjust time? Can it be oil changes gone afoul? Who knows. Lots of anecdotal stuff and comments out there but this should not be happening if the complaints are true.
