I'm considering getting a used 2016 RS7 and had a couple of questions...

1. Can anyone recommend a good third-party pre purchase inspection company? (I will be buying the car out of state, sight unseen)
2. It doesn't list that it has the 'Dynamic Package', is that a must-have package? (red calipers, anti-roll suspension, etc... It does have the sport exhaust)
3. Is $77k (asking price) too much for a 2016 with 22k miles? (car is mostly loaded) If so, what's a good price to pay?
4. Any known issues with this model year?

Thanks!
