just out of curiosity i really do not mean any disrespect i dont really know much about the history of the 98 s4 but how do u honestly think your car is worth as much as a brand new $70,000 RS4...i do understand your car probably has a lot of sentimental value so that makes the price higher in your mind but lets please be realistic here...A. modding contrary to our minds actually reduces the value of a car and B. and again no offence but your car isnt that clean ie. driver seat looks like it has been through hell
