The BMW has the nicest, most legible gauges of all the ones shown here. The Porsche appears to be the most cluttered.
However, I agree that the junk in between the dials should be moved to below the dials. And, though the Porsche layout is cluttered, it at least contains one of the most important gauges in any car: oil pressure.
The lack of oil press and water temp on the M3 (and BMW in general) is a major shortcoming. Water temp is far more useful than oil temps, as a problem in the cooling system (i.e. leak or blown hose) would show up in coolant first.
