hello i have a blue 1997 s500 that has a bad motor. and i also have a 1995 white s500 that has a great motor. the 97 has a clean tittle and only has 2 owners and the white 95 is salvaged but still has a great engine but has had a phew owners. i was wondering if the 95 engine will fit in the 97? and also how much would a swamp of the 2 engines cost me? thanks for the time and info.
