heh, but if you plan on bringing them to court, hope you have evidence, if any. Did THEY rebuild your engine or did YOU do it yourself. Courts might just say, it was your working or whoever you hired to rebuild that was at fault for a faulty engine and the shop that supposedly "blown your engine" probably have no prior history of your car ever being worked on in the past by them (which would cover their own ass) ..if there was and you have reciepts and history showing, then you could prob win. If not, i dont think you have a chance in hell.
