Would be the aux, iPod adapter and the Bluetooth connectivity.
The mirage is a great compact car, the maintenance and upkeep is very budget friendly. You can actually fill up the gas tank on empty with about $25 depending on gas prices. You worry about oil changes and tune ups about every six months and that can run you between $35-$100 depending on where you go. It is a really reliable car. The comfortability may be the only issue because it is a rather small compact car, so long road trips would not be ideal in such. Since it is such a small car the engine is very close and actually very loud. If you don't have your radio turned up the entire ride you can literally hear your engine at work. Your back seat is not an ideal back seat, so passengers may feel uncomfortable and cramped during the ride. The cushions are very firm and give you sense of sitting up.
