2004 civic goes in for diagnosis work. Informed that timing is 180 degrees out and other minor work and leaks. Quoted almost 3k to fix. Deny service. Owner asks to buy car for $500 plus my diagnostic bill.Decide to do work myself. Check timing,it's dead on. Change and clean egr valve and put on new exhaust manifold. Car runs fine. Shop is either run by crooks or idiots
