I bought my 2014 TrakPak in December of 14 with 2000 miles from a Chevrolet dealer. The original owner traded it on a Corvette. The sticker $37.5 and I bought it for $27k although I have no idea what the original owner paid. I sold it not quite 2 years latter for $25k although I had put about $4k in mods on it.
Just for fun I went on the Vroom site last night and filled out their form for my 19 PP1/A10 with 9,899 miles, red leather Katzkin seats which has been a garage queen since it came off the show room floor and was offered $40,008.00, where Carvana only offered $36,500.00! I paid $36k in June of 19 when I drove it out of the showroom, and sticker was $43k. If they’ll actually give me is yet to be seen, but driving the Mustang for 2 years and making a $3,500.00 profit is sure appealing.
