"Overall, the Audi S5 is an amazing car. The only problem we had with it was the thermostat needed to be replaced and the convertible top has a poor design. The rear window tends to come unglued and the headliner falls. We paid $650 for the rear window to be glued and the headliner to be fixed. The car overheated the day after we bought it, so the place we bought it from replaced the thermostat for free. Very fast car though. I love having the power!’ Gas mileage is terrible. "
