We owned a LC. It got 10-12mpg average city, 14mpg highway and did 0-60 in about a minute! Didn't stop worth a crap, but was very comfortable and was never in the shop other than normal maintainance and one of the most reliable cars we've ever owned. Our 4.4 gets around 19-20 highway doing about 75-80.
