My Audi A6 is always clean and well maintained. It is full loaded with navigation updated to 2014 maps, sunroof, dual climate control, automatic heated leather seats, Bluetooth for phone calls and Aux jack to plug your phone in for music. I also keep a car charger with cables for an iPhone new and old, and micro USB for android phones.
I try to keep the tank full for when you use it. I use premium gas and would request you do so as well upon return if needed.
