So I'm days away from taking delivery of my new leased 2013 X5-35d. First time leasing and not familiar with all the paper-work and "options". Are there any pitfalls or (unncessary and) costly "options" to be looking out for? I know they will try to "sell" a tire and wheel protection, anything else? It's a 36 month lease with the intent to return the vehilcle upon lease end. One more question: Are carpet floor mats included or offered "for purchase" ?
