It's "Jack of all trades, master of none" syndrome. Porsche still has 4 vehicles in their lineup to worry about, that's it. Each one of them beats the sh*t out of the competition. It was the same when BMW had 4 vehicles to worry about (3,5,6,7). It's hard to be the best when you juggle ... oh, who can keep the count ... different platforms and vehicle lineups. However, if it weren't for this, there would be no BMW.
Let me see the hands count who would pay $50k for a killer but entry level 3 series BEFORE ANY options ... nobody ... really,nobody? Yeah, thought so.
Oh, by the way, your 2001 E46 might have costed 40k well optioned. That's not exactly the same as 2012 F30 costing 40k.
