Bro I have seen 2 wagoneers which might interest you, I don't know any details about either of them so you might want to go check them out:
1) Blue wagoneer standing in Phase 2 DHA when heading from Gora Kabristan towards Korangi flyover, parked since 3 months on the truck stand at the left of the road just before the Europcar garage.
2) White Wagoneer standing at mechanics shop in Gizri after the Gizri playground on the left hand side of the road, it belongs to the master ustaad at the shop.
Other than these:
There's a Wagoneer pickup standing at the connecting road from Gizri to Zamzama, pretty shitty condition but if you just want the chasis it might be the one for you.
Another Wagoneer, when going from Mai Kolachi towards SherShah / Hawkesbay, on the right hand side there is a cluster of mechanic shops near People's Stadium, I have seen a Wagoneer here on and off, don't know who it belongs to, as far as I remember it's maroon.
