Hi Doc, a Townace is a lovely machine and the way you describe yours, it sounds trouble-free. For a people carrier, a Townace seems more practical and I assume, its maintenance would be quite convenient in Abbotabad. CNG makes it economical as well
A Pajero, on the other hand, is an amazing machine as well, with its own set of benefits and problems. It is a perfect people and luggage carrier as well with lots of power. I guess the maintenance would be slightly more expensive than the Townace, if you keep it for occasional use only.
I believe a Pajero is more stylish and powerful. For a family carrier, i'm sure the kids would love it. On the other hand, Townace is probably more comfortable, with each seat having its own armrest, multiple AC ducts in the rear, and easier for elders to climb on to the vehicle due to height of its steps.
I hope I have not confused you even further :p. Whatever decision you take, please update all of us as well :).
