XFE (5 speed) is tuned for highway driving. Flat terrain at 58mpg = 38-42mpg. Subtract 4-5 mpg for air conditioner! Poor in town mpg (23-26). Not good for stop and go commuting in a hot climate. Enjoy XM radio. Good seat adjustments (up/down, back-forth, tilt-lumbar). Chevy. Get rid of Coupe design. Dangerous, cannot see out of back, especially with worthless spoiler. Change to hatchback. Trunk is deep, but opening is miniscule. Can't even put a standard cooler chest in it. Poor access to rear seats. Also Chevy failed to support the XFE sedan. Could not find 1 in the whole US! Corporate didn't know either. Inexcusible. No wonder they are bankrupt!
XM radio. Cruise control on 5 speed.
Get rid of coupe. Change to hatchback. No spoiler. improve trunk. improve placement of rearview mirror. Have variable electronic tuning, to improve city mpg. (city/hwy switch). Improve aircon, so it doesn't use 4-5mpg.
