In general I'm very happy.
I've changed a 140PS VW Passat for mi Cali Beach also 140PS, same engine both of them, but obviously many differences in gearbox, chassis, etc...
As you can imagining my former Passat was more nervous than my Cali and quite more light so I almost never needed to change to 5th gear climbing an slope, which I have to do with my Cali when road are very steep. In Spain, in some mountain roads, even had to change to 4th gear. Apart of that 140PS are more than enough, I never need to change from 6th gear.
Not done yet a proper off-road trip to test the 4motion but I think in this case 140PS will be enough. Again horses for courses, the Cali has no a quite low gear so the 140PS is not the main issue.
My conclusion is that if I were buying now and new Cali, maybe (not sure), I would buy a 180PS one. In Spain you can buy a Cali Beach 4Motion 180Ps manual gear, but I didn't because I though this engine was not mature enough and went for the reliability of the 140PS.
One more conclusion is that I'm no longer drive as use to do with my Passat, horses for courses, a Cali is a van and mainly a recreational vehicle, so when driving it I do more quite.
