Unusual to find an S4 in this condition, Engine is stock with no map alterations, it does have an aftermarket air filter but otherwise standard, grill has been changed for the honeycomb option but the original comes with the car, daytona grey with black leather is my favourite combination and still looks amazing, very well maintained and low mileage, I had all the big service items done last year including gearbox oil and filters, brand new Michelin pilot sport tyres, in my opinion this is one of the best S4s available
