Information about Alfa GT 2,0 JTS

so people, it may be that I may soon have to buy another car. and if so, then it should finally become an alpha! in visier: alfa gt. I have the following questions/points, where I like to need infos or experiences: 1. base 156 or 147? 2. driving power 2.0 jts versus 1.9 jtd (0-100, topspeed) 3. consumption 2.0 jts versus 1.9 jtd 4. reliability. I suppose, timing belt is a topic like always (so change on time), but one hears again and again the “legendary” 2,0 ts (155ps) should be the least stable 2liter. how about 163ps jts. oh, the car: about 1 year old, 20tkm, black, leather beige otherwise I don’t know anything. look at the box at fr/sa and try it. thank you for your input in advance, harley13
