The 2.5 Manual Has Enough Power
 The 25 liter 6 speed manual trans. offers gear ratio's which are correct for the nenine. I get 20 mpg around town and 27-28 mpg on the road. I have heard complaints about the power.  I live in the Rocky Mountains and have not trouble with power as well as no trouble with passing.  Perhaps, drivers don't like the managing the power with a manual transmission.  It takes deep snow well and will do a good job in mud (we have both).  I replaced the original tires at 20,00 miles with Kelly Navigators; good tires!  The only problem I have had is the seat cover on the drivers side cracking.  It handles so well I think many sedans would be poor by comparison.
