4S店要拿新Q5换我的老Q5，什么套路？

以下是dealer邮件内容
We often receive requests for pre-owned vehicle
models similar to yours. According to our records, it appears you have
approximately 12 payments remaining on your 2017 Audi Q5
and are paying approximately $x,xxx. 

Being able to acquire vehicles that we have either sold, serviced or both that
we can add to our Pre-Owned inventory is the best possible scenario. In a
search of our customer records I identified your car as a perfect match for us.
As compensation to you, if we could upgrade you to a newer Audi Q5
keeping your payments about the same, would you consider letting us purchase
your car?
我车是最后一批老Q5，2.0T，顶配加特别轮毂，很漂亮，街上比较少见，4年+4年延保，100k mile，五年prepaid maintenance.  老Q5用的是采埃孚（ZF）8AT发动机，全时四驱，德国造。新Q5是7速双离合（貌似口碑不怎么好），智能四驱，墨西哥造。

估计他说的“a newer Audi Q5”是款式新，未必是新车（我可能想多了哈哈），不太可能是车龄更短的老Q5，因为几乎不存在比我车龄还短的老Q5了。
不知道各位大神什么看法。
