$1800 repair. Is it worth it? My Nissan Pathfinder has been a great car with few problems. Now it needs an exhaust manifold leak repaired in order to pass emissions. I'd say "no way" to the cost, but I've heard Nissans have much longer lifespans than other kinds of cars. I'm wondering if any mechanics or car enthusiasts can advise me about whether it would be more cost effective to fix it or to replace it. Thanks!
