Sorry to extend the non-relavent discussion, but....Question: Are the same options/standard features the same between the US and Canada? I don't think they are.
According to Ford.com(the US version), the Sport has the Bliss and Tow package, AWD standard, but it doesn't appear the inflatable belts are standard.
On the otherhand, the Limited appears to have Navigation, Heated wheel, power adjust pedals...and a few other things that the Sport has as optional. It's also standard as FWD.
Both have infatable belts as optional and as Hugh and 613GT500 has stated, some options are not available on the Sport and vice versa.
In the end, the newer models(Sport and Limited) have different standard features and different options, but Ford has closed to gap on the available features between the 2(earlier models gave the Limited more options). But, to say a stock Sport has more standard features vs. the stock Limited is not necessarily true, just different.
