Cost & Ownership Comparison
The W212 is cheaper to own than the W211 over a typical five‑year period, despite its higher purchase price. The W212's better fuel economy (especially with the OM651) saves around £200–£400 per year, and its more modern emissions systems mean lower VED in many cases. The W211's lower entry price is tempting, but the risk of OM642 swirl flap failure (£500–£1,200) and oil cooler seal leaks (£800–£1,500) can quickly add up. The W212's OM651 balance shaft is a known issue, but it's less common and generally less expensive than the OM642's swirl flap problems. Over 50,000 miles, the W212 typically costs its owner £1,000–£1,500 less to run than the W211, making it the more financially sensible choice in the long run. For those on a tight budget, a well‑maintained W211 with documented engine work can still be a good option.
