The basic difference is that quiet can mean little or no noise, but silent means ZERO noise. If you describe somebody as quiet, it means that person doesn't talk very much. People can also talk quietly (with a very low volume) but itís impossible to talk silently!
Though some may consider the Ford Flex a crossover, its really just a funky wagon. Not since the original Scion xB have those two words adequately described a vehicle. And while the xB got flabby and soulless, the larger yet tidy Flex is a credible effort for Ford plus all wheel drive is offered. Yet, unlike the trillions of Explorers littering the roads, the Flex doesnt shout its status as a winter car with hiked up ground clearance and knobby tires. When you just need extra traction on regular roads, the funky Flex will do just fine.
