Cars 6180–6181 were fitted with a vinyl wrap, which replaces the brown painting on the sides of the cars. On the inside, new resilient flooring and new blue seats were installed to match the new 7000-series cars. A dozen 6000-series and 3000-series cars received these features. If the pilot program goes well, the remaining cars will be given the new look. WMATA says repainting would cost $14,055 per car, while implementing a vinyl wrap costs only $4,776. Metro's Richard Jordan also claims this method is more environmentally friendly compared to painting. The aluminum surface requires harsh chemicals which have to be treated before put down the sewer.
