I had reserved a Jeep Grand Cherokee, but upon arrival at the store, I was told it was unavailable. I was offered a Hyundai Santa Fe instead. Wanting an American car, I paid extra to upgrade to a Ford Mustang and specifically requested a V8 engine, which was confirmed. However, I received a convertible model with a V4 engine. Had I known it was like the domestic version, I wouldn't have paid to upgrade. I felt misled by the staff.
