I'm considering trading my white/red 2017 Q60 Sport with 45K miles for a CPO 2017 Q60 RS with 28K miles. It is loaded, blue/white, carbon fiber accents (spoiler, side mirrors, etc). It is in excellent condition (the previous owner had two other cars). It just came back from lease, and the sales manager said that it will probably price at $38K. This car is exactly what I want, and I have 3 months left on my lease, so I might be able to get them to eat the costs. Is there room for negotiation here, or should I wait? Any and all feedback is appreciate. Thanks!
