I purchased the RDX 2 weeks ago with 7 miles on it. It now has nearly 1000 miles with combined city and highway miles. The day after I picked it up I drove 550 miles and averaged 23 MPG. 90% of the time it was downpouring rain in the mountains of WV and VA. I've been averaging 18 MPG around town however I do not sit in traffic very much. I had a Civic and it was a great mode of transportation. However, the RDX is a driving experience with immense pleasure from the XM radio and sound system to the handling and comfort. Also got the protection package, wheel locks and tow package.
Sound system, handling, seats, fit and finish, ample luggage area.
10-20% better mileage, regular gasoline or a diesel.
