Mercedes E-Class

The Mercedes E‑Class is the executive saloon that balances calm refinement with a hint of sporting intent, wrapping luxury in tasteful understatement. It pampers occupants with a composed ride and intuitive tech while quietly reminding you that it’s still very much a Mercedes — authoritative, polished, and unwilling to shout for attention.

Very comfortable car but mechanical reliability is non-existent!
Major breakdown that left the vehicle immobile for 10 days (turbo failed). Repair cost was outrageously high: €8,301. Three weeks later I'm told the rocker arms and the camshaft need replacing! I'm waiting for the quote, which promises to be hefty. I should point out the car has always been serviced at the official dealer network according to Mercedes' recommendations. Avoid it! And not a single goodwill gesture from Mercedes. It was my third E‑Class but now I'm changing brands for good. NEVER EVER Mercedes again.
