BMW 5-series

About the same time Mercedes began selling the W210, archrival BMW introduced its revamped E39 5-series. Like the W210, the E39 was also a very successful car.

As is typical with BMW and Mercedes, the BMW 5-series is more sporty and the Mercedes is more luxurious. When choosing between the E-class and the 5-series, consider whether you whether you are willing to make the luxury/handling tradeoff. Note that the W210 suspension (shocks & springs) can be modified very easily and inexpensively to outhandle the stock 5-series.

BMW installed a variety of inline-6 and V8 motors in the 5-series. The inline-6 configuration is naturally balanced and therefore inherently superior to the V6 configuration. Only a V12 (two inline-6 engines in a vee!) is naturally smoother! While everyone else — including Mercedes and Lexus — moved away from the inline-6 for cost considerations, BMW turned the motor into an integral part of its brand identity.

In terms of reliability, the Mercedes probably has a slight edge. Many W210 owners with BMW E39 experience report that the W210 is more reliable.
