BMW of El Paso

Went in to purchase a new mini cooper, sales associate was all over the place, i kept asking questions about how the paper work and financing was coming along and just got " dont worry everythings fine" i asked who i was financed with and wouldnt get a answer, i drove off the lot with 1/2 tank of gas when i was expecting a full tank as promised. i also only had two mats in my brand new car, where i was supposed to have four. if all that wasnt enough 3 days later i realized that i had been driving around with no inspection sticker. i called the dealership and they apologized and had me go in and waste more of my time to get the sticker that should have been givin to me at the time of purchase. BMW should cut out this mini dealership as ive seen online they are getting terrible reviews and are bringing a good name down with them.
