singson your a fool. your talking rubbish... what cars do 60+mpg?? most cars don't even do 40mpg... yes american cars are well known on the whole for not doing that many mpg than others.
Your comments on auto vs manual...
In america the roads are quite straight, and speeds are what, 55mph max? whats the need for a manual? i could do that in second gear in a 1.3l engine. + if there is a lot of traffic, your gunna have to stop and start at lot more, and unless you actually drive, then i doubt you know how much that hurts your left foot after 30 mins.
1 thing i will say is that american cars don't really know how to go around corners :P hence drag racing and nascar *yawns*
