I was just at the dealership yesterday and I was talking to him about a new suspension for my '94 525i...He said that my car would drop in price when I go to trade it in or sell it because it wouldn't be factory "BMW"...what is everyones take on this and if that's the case, why can't I throw a 540 or ///M5 Suspension in it? -SC- '94 525i Sharked
