My recent M5 v. Alpina B10 post took a look at two exotic versions of the E34. Of course, BMW offered their own alternative to the M5 late in the production cycle, as the introduction of the M60 V8-powered 540i produced nearly as much usable power as the more expensive M variant. Such was the success of the 540i that BMW initially judged the M5 dead in this market; it was removed from the U.S. in 1993 after slow sales and wouldn’t return until the new millennium.
As a result, the 540i flew the 5-series performance flag for two generations and still is very popular today. Especially in Sport versions, the E34 and E39 540is offered power, refinement and outstanding chassis dynamics in a package that was attainable for more people. So which is the better buy today – the first or second generation?
