Thanks for the great site, read and learned alot before finally buying a hybrid. I sent an email in also, but can you add both a 2 and 4 WD option for the Mercury Mariner just like the Escape. The data base shows both but when you go to enter a new hybrid there is only the "Mercury Mariner" option no 2 or 4WD breakout. I am tracking milage but it is not being added to the 2WD Mariner database. Thanks
