I don't think the comparrison chart is right.

It lists both the base and limited coupe with 17 mpg city and the base getting 25mpg on the highway and the limited getting 21.

FWIW I've been getting 24mpg with my 05 Limited, (manual in town driving).

For others, here's a link to the chart form, the MPG is listed under Powertrain (It tough to find, sorry no direct link)
