I am also in the DFW area, and rent from Enterprise on a regular basis for work. They have an unlimited mileage policy if you drive the car in Texas, and into any state touching Texas.

Call them on their 50 mile limit. My previous car was a Pontiac, and the dealer in Minneapolis also used Enterprise... again no limits on mileage.

Who is your dealer, so I can avoid them? I purchased the car from Huffine's in Denton, and so far, I am very pleased with their work, both on the XFire (only an oil change so far) and our Jeep Liberty.

Best of luck!
