I went thru this process this year....First with a 2016 Legacy Premium...Original owner and always dealer serviced..Had 95k miles on it.Sold it to Carvana for 12,100 back in March..Carmax offered 9k and Kirby Subaru of Ventura offered 7,500...Bought a 21 WRX Premium CVT thru Costco Auto program..After three months just couldn't handle the bumpy ride.....Sold it to CarMax for 30k in July.Even the Subaru dealer told me to sell it to Carmax for more money.....Now have a 22 Legacy Sport...Miss the power but love the smooth ride ......When I sold the 2016 Legacy back in March to Carvana they wanted three things: driver license, clear title and a picture of the mileage...Since I still owed on the 21 WRX I didn't even bother checking with them....I did consider a 21 Mustang GT but Ford raised the price almost 4k from March to July the way I wanted it equipped so I picked the Legacy again....Figured I lost 2k in the trade in of the WRX after getting the refund on the extended warranty I bought with it...
