10-Year-Old Luxury Car Hides Repair Pitfalls: Owner Discovers Shoddy Work During Oil Change

A man purchased a used Mercedes-Benz and, during a routine oil change, unexpectedly uncovered serious issues from previous repairs. According to Canadian TikTok auto repair influencer Cxllmedez, the car’s oil pan had been haphazardly sealed with a silicone sealant resembling bathroom caulk—despite the original plastic oil pan not requiring any additional sealing at all. Furthermore, an incorrect aftermarket drain plug, mismatched bolts, and improper washers were used, causing multiple oil leaks. The blogger emphasized that older luxury vehicles can harbor significant hidden problems if they haven’t received proper maintenance, urging buyers to always use reputable repair shops and arrange for a third-party inspection before purchasing. Online commenters echoed the warning: luxury cars demand consistent, professional care—otherwise, the money saved on the purchase price could easily be swallowed up by costly repairs.
