Lost - Sem Saída

all in all it was a pretty good flick,but a few questions need to be addressed;first off he was driving a brand new something perhaps a BMW i dunno couldn't really tell, but he did run low on fuel and had to stop and fill up,but later when he was driving the 1980,81 ford f-150 p.u. gas was no longer an issue.(i drove one of those gas hogs for years),and his ran pretty damn good for $500; 2.if archer was such a good Apache tracker why couldn't he see the rush cover-up job that Stanton did with his tire tracks in the sand when he hid behind the billboard? i mean the apache man did see a cigarette butt on the highway while doing 70!; 3. how in the hell did archer figure out he was using g.p.s. and Judy at that? but in the end i thought she was working with the feds and was leading him into a trap for a reward.
