In the Great Gatsby,is Nick a reliable storyteller? why/why not?

Nick is a pretty credible character/narrator. He doesn't have any eccentricities and seems grounded. He was educated at the Ivy School Yale and fought in WW1. Nick isn't a character who needs anything. He seems to have enough money to settle down in West Egg. He has come to New York for work and to learn the bond business; he doesn't seem to be in a hurry to get started. Nick seems to pride himself on reserving judgment although he seems to have his opinions. We can,however, forgive him for that-East Egg is a very surreal place.
