I find rare vehicles, if you need help finding a car or a bike or a boat, maybe even a helicopter I'll try to find it as best as i can and post an accurate location for it if found. I have found a hell fury, sultan rs, and sentinal xc so far and I will be searching for new things to find.
Hellfury found in front of red building just past brucie's lockup.
Sentinal Xs can be found a little south of playboy's loft on 2nd island.
Sultan Rs was found behind aldreny mansion on 3rd island upper right corner of map.
