Hey guys I have an 05 E500, I love it's a great car but I was wondering how hard would it be to replace the engine with an E55 motor, I know you'll going to say "Just sell and get an E55" but where I live the E55 is WAY more more than double. Anyways a friend of mine is a wrecker and they just got a smashed E55, it was smashed from the rear so the engines alright. He's giving me a great price on it, I have 8 days to decide. This got me really thinking cos the labor would be done by him he pulls car as a job. I could probably find a buyer for my E500 engine somewhere down the track too so yh. I asked him if I could plug all the electrics into my E500 so in other words would my cluster, ignition, jeys, head unit etc work? Do I have to replace all that because that's where it'll get expensive. What's there to do in terms of electrics. I'm getting this engine for a very good price I will never see again in the near future so what do you guys think. By the way PLEASE PLEASE don't ask me to sell it and get a E55, it's WAY WAY more expensive to do trust me.
