The cavernous Quest is powered by an eager 3.5-liter V6 mated to a continuously variable transmission. It is the most luxurious minivan on the market, with a plush and quiet interior and a smooth, compliant ride. Just don't expect sporty handling. The two rear rows of seats can fold flat to form a convenient, flush load floor. But the Quest seats only seven at most, not the more useful eight. A covered cargo bay behind the third-row seat can hide luggage, an uncommon feature in a minivan. Reliability has been average.
