Purchase advice Ford Mustang 3.7 V6 2014

Hello dear community, I need your help I’m looking for a new everyday car with a little bit of strength under the hood and an eye-catcher he should be too. Found me the Ford Mustang 3.7 V6 very attracted me. I find the Mega. After a few hours looking around and researching info I found out and often read that he did not consume as much as expected. I have often read from 9 liter kombi to 12.7 liter kombi n. and of the everyday suitability that he adapts to every driving style no matter whether city highway or country roads. jzt to my question what can you give me so from infos is that with the consumption ? is the everyday suitable? and if I get it then with lpg plant or not ?! and what is the “shaker” which stands with some or “stabis” or reinforced cardan wave I have already read ? there are ed differences between build year 2012 to 2014 ? or 2013 to 2014 ? how does it look with service from ? what are there for costs? and etws very important still for me because I live “unfortunately” in Austria and I have to pay import tax because of the exhaust gases, I need to know how much Co2 emissions in grams which gives out because I could find this nowhere? Please help me and please leave this with the why ned immediately a V8 I find 300 ps are for me no more I do not need and I do not want to. Thanks in advance
