 After more than 2 years and 20K miles, I can say this car has been great. Excellent acceleration and handling. The sports mode allows for more lively driving. The quattro system is great on curves. No problems with anything and have gone in only for routine maintenance. A few years ago A4s had some problems with oil consumption, but I have not had that problem with this 2015 model and it's possible Audi solved whatever problem was ailing earlier models. Bluetooth works well. My only critique is that the technology is not as good as some other cars (e.g. no backup camera), but I care more about speed and handling than technology. Mileage is really good on the highway.
