Elasticity: 9-5 2.3t BioPower Deer vs. 9-5 Aero

Hi Together, it’s about elasticity (i.e. passing by gas) and consumption values at “9-5 2.3t BioPower Hirsch” vs. “9-5 Aero”. In both cars I mean the current “chromoglasses”, both with the same circuit. I have 4 questions 1.) Which of the two vehicles can be used less in everyday traffic? (Overland + some city) 2.) Does one of the two have the significantly better pull-through values? ( Overtaking, acceleration ) 3.) Is a price slip noticeable or a look at n? (especially for dealer vehicles that are on the farm) 4.) Did Saab / GM turn out for spare parts supply? Background my question I would like to submit my 9-5 2.0t BioPower Kombi in January 2010 and buy a 2.3 BioPower with Hirschtuning or again an Aero (260hp). Whether this is reasonable in the current Saab situation, I can probably only answer in a few years…
