Our take

What it really is

The last driver-focused rear-wheel-drive BMW before the switch to turbos and AWD. The N52 inline-6 is one of the smoothest engines BMW built.

Why it's on this list

RWD balance and a proven I6 at used-car prices. One of the few luxury sedans in this price range worth driving for its own sake.

The honest trade-offs

Premium fuel, premium parts costs. HPFP failure on early cars, cooling system components need proactive replacement. Carbon buildup on direct-injection engines.

What to buy and what to avoid

Get the 328i with the N52 naturally aspirated I6 (06-11). Skip the 4-cylinder 320i. Manual is the better choice. Verify CPO history if you can find it.

Annual cost of ownership

Premium fuel. Includes coolant expansion tank, valve cover gasket lifespan costs amortized.
