Decision-making aid Omega Caravan 2.0/16V vs 2.2/16V

Since we now have a good 2000 Euro together, we are now looking for an Opel Omega Caravan. After having already looked at some vehicles, when we did not have the money together, it is also certain that the car in our opinion can not cost more than 2000 €, under certain circumstances max. 2300 €. To the selection stand for us the Caravan 2.0/16V with 136 hp, year 1998-1999 and the Caravan 2.2/16V with 144 hp, year 2000-2001. I had not liked the 2.2er for the first time, however, the more I look at it, the better it pleases me. Therefore the question: Which would you decide for now, if both with Tüv, mileage, maintenance, equipment etc are approximately the same and why would you decide so?
