Hello,my english is not perfect so sorry,hope you will understand me.I crashed my cl500 a bit lol.I will need to replace some bottom parts,engine oil tank broke too.So I kind a dont want to get rid of my cl so I thought I might just repair it,people said it might be costly but,well whatever maybe.Btw thats 2-3 minutes after turning esp off,idiot friend advice,was driving pedal to the end all the time these roads,never felt any danger...Anyway..So the metal part engine stands on have to be replace,some other driving stuff,some front metals,radiator and so on.Well it might got fixed,thing is now I started to think,didnt my engine broke too? Under hood it doesnt look bad,just the radiator and cooling fan.After crash engine wasnt working,but today I looked under the hood and all engine belts are fallen off,now im starting to think,if engine spin for at least a second without belt automatically engine failure? I was thinking it would be sad to fix all the problems that there is and at the end find out engine failed too.Maybe somebody had similar crash,what chance do you think about engine failure? I have no freaking idea when engine stopped working or when belts fell off..and there is no way to test now when everything is broken...Anyone had similar accident? Another question,could I replace my s500 engine with s600 engine + ecu or there are more problems? If id go through all the pain and then found out engine damaged adding s600 engine would cover feeling all the bad and expenses,not even sure its worth repairing but i like my cars i have feelings for them so.
