An amazing vehicle: mid-engine, supercharged, all-wheel drive, 7-passenger with plenty of room, yet 2 inches shorter than the Camry! This was our 2nd Previa. The first was a 1992 LE AWD. We bought that one with ~37k mi, sold it with ~150k mi, and last I knew, it now has over 220k on it. I bought my '97 with 50k mi and it now has 164k. It has been VERY reliable (as was the '92) and I would buy another if they still sold them. The Sienna is nice, but it is longer, lower, and the AWD model has those stupid/expensive run-flat tires.
Reliability, SUV height and room with compact car footprint, middle row captains chairs that can be faced forward or backward.
