Hi; Wondering if anyone has tried the Bombardier code recently (c302100)?

I need a car at LAX for a couple of weeks in March (3/3 to 3/17) and it shows a great rate- $273 for a full size for two weeks, $400 including all taxes and fees. But of course I don't want to be embarrassed or hassled. I am a Preferred member, so in theory I can just waltz out to the parking lot and jump in the car. Has anyone had any trouble recently?
