It is a case of sold as seen which does suck... Best thing is give him a call an see what he say's, explain the prob's an that you were now advised about prob's you found.. Dash lights should be easy fix an exhaust bracket, say about wheel enlinement an cost an ask if he is willing to help you with it, no harm in asking an he might be decent to help, if not then a barrage of abuse in his face...
