@ smarticus - well, I'm looking for something that goes beyond the local 'norm' of 20-30 MPG. US cars do appear to be on average much larger than what I'm used to seeing (in Africa and EU) - so that 'weight' aspect seems to cut into the general MPG.
But again, the US focus seems to be on 'power' and horsepower more than MPG. To me if its a lawnmower engine, does its job, and doesnt fail, that's good enough

I'm still mulling over the idea of diesel, given that a deal with some local junk food places could provide all the oil needed to run a vehicle, quite easily, for next to nothing.
@ NCC1701 I'm used to the idea that driving well, wearing a seatbelt, and maybe an airbag fitted, is all that's needed. Beyond that, *shrug* its in the hands of Fate. Not a big deal. The last thing I'd do is give into the irrational fear that a lot of car manufacturers seem to like whipping up, and which 'coincidentally' result in decreased MPG, and require increased gas consumption. A very convenient coincidence for the auto industry and big oil. So I interpret the idea of additional safety features - as deliberate attempts to keep people from making good choices as regards small fuel-efficient cars.
/rant off :P
I've driven in some genuinely dangerous-driving regions in Africa and South Africa - where each Christmas season, for instance, its normal for there to be upwards of over 1000 deaths on the road, up to 1500 some years - so the US is ridiculously safe and well-behaved in comparison.
@ SmartTech - thanks for that info re Euro smartcars. So it's the horsepower difference. Hmm, anyone know why they increased the horsepower? Was there any good reason (to impact on MPG) beyond the 'my engine can go faster/louder/noisier than yours'? I guess I'm the last person in the world who's more interested in MPG than anything else
thanks @ all for the feedback, its really useful.
