We leased our Malibu on June 5th, 2005 (It's our fourth Malibu lease in a row, dating back to 1997). We like this year's design best of all. My only regret is that we did not get it with the sport package. It runs and handles very well, with plenty of room for rear passengers, and room in the trunk. We are getting about 21mpg. around town, and about 30 mpg. on the highway.
On board computer that calculates the miles per gallon you are getting, oil life left(in %), range of miles left for driving with the gas you have in the tank, and outside air temperature. The two trip odometers, and radio that gives song titles (if the station broadcasting has that ability)
Altimeter so you know your elevation above sea level( would be fun when driving through the mountains!)
