I just bought a 2011 GT with 46k, premium package, Brembo brake package, shaker 1000 with sync.
It's race red with white stripes, immaculate inside and out. I paid 17900 did I do alright?
Well used car values do vary depending on where you live. I'm on Long Island,according to Cargurus.com GT Premiums within 100 mile of me with similar mileage as yours are going for 19k-21k. So I think you do good. Enjoy the car and welcome to Stangnet!
