The bottom line
Oil leaks hit 87% of these E-Classes, so your first move on any example is a cold under-hood look for seepage plus a drive to catch fuel-trim faults and odd noises. Active error codes are the next red flag, so demand a full scan before talking price. The 90% repaint rate hands you clear negotiation leverage on cosmetics, especially with zero structural repairs in the mix. Walk from anything already needing major engine work—the spread of mediocre and poor cars means plenty of money pits are sitting out there.
