I'm in Culver City and commute to Santa Monica each day. I've had my CT since early March and 38 mpg is about right for this area. There are several threads that discuss the why's and wherefore's of this. Let's just say that the situation here on the West Side is somewhat unique and a bit of a challenge to getting optimum fuel economy!
2.1K miles on the car in hot and dry Texas- 45.4 MPG. I have noticed as the weather has cooled down a bit the MPG's are going up. Just filled up yesterday 7.1G @321 miles 45.2 and gauges today are showing ~48's.
