Yikes! $1000/month for a Q5??
Q5 residual value can vary signficantly by trim/line and believe Prestige is the lowest out of all at 49%. Check Edmunds or search the forum as there were a few recent threads.
Not sure if you are stuck on a Q5, but you are unlikely to get a “deal” due to the high MF and low residuals which cannot be negotiated. For example, you could likely get a X3 signficantly cheaper than a Q5 at this point especially if you are open to a demo/loaner.
