I am nearing a decision to order a new E70 4.8. I had three questions which I want to double check against the dealer perspective: 1) If the sport package is ordered, is it possible to delete the anthracite roof liner (wife thinks it darkens the cabin too much). 2) Does the rear entertainment DVD player still come with wireless headphones--brochure is silent; dealer says yes. 3) Has anyone substituted the one rear entertainment DVD player option for two units in the headrests? Any thoughts about whether this may work better for second row passengers? Thanks for any input!
