The bottom line
These E-Classes nearly always hide oil leaks and often throw active codes, so start every walk-around under the hood: look for seepage, listen for odd noises, and scan fuel trims before you even open the door. The 90% repaint rate signals most have been touched up after scrapes or detailing, yet zero structural repairs means the bones stay sound—use the paint history and those engine faults to negotiate hard or walk when leaks look advanced. Factor fresh tires into the deal and treat electronics gremlins as expected rather than deal-breakers.
