my cars in a tuning place at the moment and the bill is slowey rising . my mate had done the head gasket and the car had only been started ands left standing for 40 mins to check it didnt over heart . now ive got it trailler to the garage to get it tuned etc , and now the next problem is its leaking water in to one of the cylinders and causing one of the spark plugs to get wet . so now they have said it needs the head gasket doing . so including a skim and new bolts etc , what should i be looking at paying ????

they have told me a price but i think its a little high considering they deal with these cars everyday ?

what should i pay ??
