The more I drive mine the more I love it. I think you meant to type 27 mpg not 27 mph. How many miles do you have on yours now? I bought my EXL navi, 2WD on 6-11-2011 and now have 5,372 miles on it. The mpg has improved over time.have the car 5 months,great on the highways,lots of pep and control.have taken it on a trip from n.j. to ill. runs great about 27 mph.on the road.
