It is hard to believe the 7th generation of the Porsche 911 has been with us since 2011. In that time it earned our love and respect by expanding the lineup and saving the manual transmission. But all good things must come to an end, so RM Sotheby's and Porsche have announced that the final 991 series Porsche 911 auction is open for bidding. This gorgeous Heritage Edition Speedster is a fitting conclusion to the series, and it reminds us that Porsche stays true to their history. All proceeds are going to the United Way, and the auction will end tomorrow at 1 PM Eastern Time. Click the button below to place your bid and stay with us for all your Porsche news.
